Amazing, especially uphill. A glimpse into the future.
I’ve been trying the Hypershell on some steep hikes and on my road bike, and I’m pretty impressed so far. The uphill assist in particular is kind of amazing. The best way I can describe it is that it feels like someone has attached a rope tow to your belt and is gently pulling you uphill. At the same time, it almost feels like someone is puppeteering your legs—lifting them at the knee and putting your foot forward for you. It feels surprisingly natural. The response is quick and intuitive, and I never felt like I was fighting the machine or having to change the way I walk. On one 2 mile hike with 450’ of elevation in the first .9 miles I was able to hold my average speed at 3.1 MPH - very cool! . Going uphill, I noticed I could really lengthen my stride, almost like I was walking on flat ground. I still exerted effort, but could move faster, cover more ground and get less winded than without. If uphill is an A+, downhill is probably an A- or B+. It definitely helps, but the effect isn’t nearly as dramatic. I’m curious to try it on a long backpacking descent and see how much it saves your quads after a few miles. Although I don’t know how much the waist belt and battery would interfere with a larger backpack. Walking backward is one thing that could use some work. The assist can kick your leg backward a little too aggressively, and walking backward downhill was particularly awkward. Not something you do very often, obviously, but I’d like to see that response toned down. I also tried it on my road bike and was surprised by how well that worked. On flats and moderate hills, it felt like the Hypershell was doing maybe 70–80% of the work. On a very steep hill, around a 14% grade, I still had to work pretty hard, but it felt like the unit was contributing maybe 40–50%. I got to the top without being completely sweaty, which is definitely not normal for me. Adjusting the controls while biking was a little awkward, but probably just takes some getting used to. It fit nicely on the bike too. The equipment arms didn’t get in the way of my legs at all. Have not tested it yet on MTB. The biggest disappointment on the bike was battery life. I expected a range of 20–40 miles but got closer to 13, after toggling down to Eco to for the second half of the ride. I’d say it was not as smooth as riding a true e-bike, but the price and the fact that you can use it in other modes (walking, biking, etc.) was really cool. Looking forward to trying it backcountry skiing! Smaller people (under 5’ or 100 lbs) may have trouble getting it tight enough. I’d like to see a petite option or some kind of kit for smaller users. Older family members immediately saw the potential to regain the ability to do walks that had become unavailable to them. Getting the unit adjusted was more difficult for them, though. The straps work like backpack straps and require a fair amount of pulling and grip strength to get everything snug around the hips. A ratchet-style buckle or some other easier tightening mechanism would be a nice, particularly for older users. Last thing: I liked that I could wear a flannel/jacket OVER the waist area, which made it less visible. So far, this is a really cool new device, and feels like a glimpse into the future.

It does "something" but not enough
There are a lot of apparent affiliate videos with positive reviews that say the hitech Hypershell does "something". Some were effusive and most hedged their positivity a bit. I tested this Hypereshell over two days indoors and outdoors. I agree it does "something". The problem is the "something" is only noticable when climbing stairs and is so subtle it barely compensated for the 4 lbs I had strapped around my waist. It was totally useless going down stairs and for simple walking on flat surfaces. I felt no support or assistance. Thank goodness I got it on Amazon because I'm sending it back tomorrow.

Great potential for Medical use and handicapped assistance. Small steps bring big strides.
After approximately one week of use, I am pleasantly surprised by the benefits provided by the Hypershell X Ultra. While it is not marketed as a medical device, I have personally experienced noticeable improvements in balance, gait, stair climbing, stamina, and overall fatigue reduction. One of the biggest benefits for me has been increased confidence while walking. I normally carry a cane and still do, but I find myself relying on it much less frequently when wearing the exoskeleton. The assistance feels natural after a short adjustment period and is especially noticeable when climbing stairs or walking longer distances. The device does not make you stronger, but it significantly reduces the effort required for many daily activities. My primary criticism involves the fitment system. The waist and leg attachments work, but I believe future versions could benefit from wider support belts, stronger fastening systems, improved Velcro quality, and larger quick-release buckles. Magnetic latching systems similar to those used on premium backpacks and outdoor gear could further improve ease of use and comfort. Overall, the Hypershell X Ultra has exceeded my expectations. While there is room for improvement in the attachment and fitment design, the performance and assistance provided have made a meaningful difference in my daily mobility and endurance. Based on my experience so far, I would recommend it to anyone looking for assistance with walking, hills, stairs, and reducing fatigue during daily activities.

Only for the fit
I’m still working on this one. The write-up doesn’t state any help for muscle challenge people. Unfortunately, the Internet does have people wearing it who have cerebral palsy or weak legs, stating that it helps them. To help you along with that idea, just understand there is no help on balance. If you don’t have the muscles to keep your balance, this will do nothing for you. That all said, it’s quite a good product, and if you’re fit and would like a little extra help, this could be for you.

Amazing power for hikes and all-day outdoor work that enables me to do much more and go further
I purchased the Hypershell X Ultra S for a major 15 mile hike with my daughter at her camp. I am reasonably fit, but 15 miles is a lot especially with a recent surgery and I did not want to let her down or slow her down. I was also a bit concerned how some of the other parents and kids would gawk at me and I did not want to embarrass her either, but I felt it mean more just to keep up with her. Man, was I impressed with what the Ultra S did for me during that hike. I felt like the whole hike was a breeze and I had energy to spare. My stride was strong, and if I sped up or slowed down a bit the movement was fluid and responsive. After about 10 minutes, I completely forgot about monitoring how it was reacting, it was that easy. Did people stare, and did I embarrass my daughter? Heck no, in fact, I met a bunch of parents who were very interested in the Ultra S and asked me how it worked. And the other kids were incredibly interested as well, asking questions which my daughter was more than happy to answer and she seemed to really enjoy meeting these new kids. I was psyched. Instead of miserably huffing it, I was meeting new people with my daughter and enjoying the hike. When we got back from camp, I decided to give it a workout in the yard. Often when I have a lot of yardwork to do, it's a whole day affair, and I'm exhausted and sore after. I was able to weed, edge and mulch, a huge area that has been the bane of my existence and trim all those bushes and trees that needed it. At the end of the day, I felt great and I was ready to spend the whole day with my kids at the pool, instead of laying around the house in pain like I would've been. I have discussed it with my elderly mother who loves to garden, but can't spend much time doing it like she wants to. I can't wait to show her how it works, and see if she can get more some extra power to do what she loves. If she likes it, I think I'm gonna buy another and give it to her. Overall, I'm extremely happy with the Hypershell X Ultra S. the quality of the product is phenomenal, and feels extremely premium. The battery life was more than enough for me during each of my major outings with it. I would highly recommend it to anyone who is looking for an extra boost, whether they're hiking, running, working outdoors, or just needs a little extra oomf to get the most out of the day. Next stop... hiking in Colorado with my Ultra S!

Not for Everyday women
This is made for men. It does not accommodate women's wider hips. Almost every video I've seen (including on manufacturers website) is all men. The only women are model thin sticks. Too bad. Statistics prove women have more arthritis and more autoimmune diseases that LEAD TO arthritis, than men. In medical journal history starting from 1960s, most studies only concentrate on men and leave out women, ie: Veterans Administration studies on hypertension (high blood pressure), cardiac studies etc. Now, probably the company wants to avoid the red tape / expense of medical regulations calling this a device for arthritis. That's ok with me, continue to call it a hiking device. But make it MUCH WIDER and let the public privately decide how to use it. Maybe one day everyday women will be included to use these exoskeletons. Sadly they've still ignored women today again.

Very Intutive Design
I wanted to get a boost when hiking laps of the training hill. This product works as advertised for reducing effort when hiking. It also has a sleek design which let me wear it in my paragliding harness. Once I tucked in the straps there were almost no snag hazards. The intuitive control means it doesn't get in the way during unexpected side to side motion which was a plus. I'm looking forward to seeing what activities I can boost over the winter. The product arrived promptly and feels really solid when you wear it. It has a one size fits all design that works for most body types. The carrying case is well designed, and you can store the charger and extra battery easily in the case. The hip adjustment needs to be brought back in when you stow it which is a bit annoying, but it keeps the size of the case manageable.

I’ve bought two for me and mom
These are amazing, you can hike twice as far up or downhill. Buy an extra battery or two if you live in a high altitude like Colorado. Try it out if you’re into long outdoor adventures or even the zoo. It’s the best exo legs on the market for regular people. It’s sleek and stylish and al cords are inside the legs. I can change the battery with it on easily after some practice. We started walking the lake trails, mom’s 62 and couldn’t go very far before I got the ultra s for her. But you might not need that much power. Have fun
