  • Solidly built and it works
Size: 330 Lb Capacity
I use this to transport my speakers that weigh 100 lbs. each and it has absolutely no problem handling them. It really helps getting them up and down stairs, and the wheels are very sturdy and smooth. It is compact when folded and solidly built, and after using it several times I have no doubt it will last me for many years. It’s a well designed and very functional product, and I recommend it highly. ... show more

  • Great Product!
Size: 330 Lb Capacity
I bought this as a gift to my father who has issues moving up and down stairs but refuses to ask for help :) This product works as advertised. A little expensive for what it is in general but worth it in the end. it's easy to assemble and only took a few minutes. The yellow handle grips arrived broke. The product comes with a manual/phone number. They immediately sent new handle grips. Customer service was wonderful! I don't say that lightly. The grips are a tight fit and the replacements will eventually crack too. Thats my only thing I wish was different. However, it's really not that big of a deal. ... show more

  • Very heavy on its own
Size: 330 Lb Capacity
It seems built for extremely heavy objects as it is quite heavy itself. I wish I had gotten something lighter and more easy to maneuver. However it is solid. I cannot blame the product for my choice. One limitation is that it is difficult to secure boxes or other objects to the dolly. I partially fixed this by drilling two holes into the bottom plate so that there would be a place to clip the bungie cords. Otherwise, there is no place to attach the cords to keep the object in-place. Note that the plate is quite thick, so you will need a powerful drill and a good bit. ... show more

  • Missing factory parts
Size: 330 Lb Capacity
I purchased the Mount-it 3-wheeled hand truck as I needed something that would help get heavy items up and down stairs without carrying them. UPS delivered it. The box had torn and gaping holes on front and sides and looked like it had been dropped and gouged several times. Despite that, the handcart inside was in very good shape, the plastic bag of parts and manual were all intact. It assembled easily. The floor piece comes connected to the handle assembly by bolts, one on each side. This is factory-assembled, as can be seen in an online video. However, the one we got had one bolt on one side with no washer and no nut. On the other side there was no bolt, no washer, no nut. I had been sent a handcart certified to lift 330 pounds in which the floor and handle were attached by only one unsecured bolt! I called Mount-It customer service who responded with an email asking for the Amazon order number and more information and directing me to the owner’s manual to identify the missing parts. I sent photos and explained that the missing parts are not shown in the owner’s manual because they should have been assembled and shipped from the factory. Their response was to ‘strongly urge’ me to notify Amazon and return the handcart for a replacement. I had purchased this for an immediate need. All the handcart needed to safely operate was bolts, washers and nuts. My prior experience with UPS suggests they weren’t going to accept for return the badly damaged box it had come in and this was going to become a big hassle. I took photographs and the bolt to our neighborhood Ace hardware. They easily identified and handed me the exact bolts, washers and locking nuts - and refused to charge me for them. All of which to say this is a very good 3-wheeled handcart and exactly what I needed. However, if you buy it, expect it may come in a box that’s been badly damaged along the supply route. Most importantly, examine it carefully before using it as my experience shows there was poor factory quality control. ... show more

  • Handles House Plants Very Well and the Seller Is Very Responsive!
Size: 330 Lb Capacity
Product works very well for moving 120 Pound Plants up and down stairs. Had an issue with cracked handles when the item arrived and contacted the seller, New handles were delivered in two days. Don't expect this to be a general dolly cart, it's best suited for moving house plants up and down stairs.

  • Not What It Seems
Size: 330 Lb Capacity
First of all, this item is very heavy. Despite the glowing description and hype, this item does not perform as advertised. When going up stairs with a load it requires constant force to keep it from rolling back down. When going down stairs it takes a circus strongman to keep it from rolling down. Save your money. It simply does not work! ... show more

  • Came in handy for moving!
Size: 330 Lb Capacity
I got to help my cousin and his wife to move into their new apartment which was on higher floor. It helped speed up the process in moving everything they packed in totes + new appliances! Only slight little grip, is that it can't make turns that easily, but it can hold 300 lbs. and climb stairs as advertised! It also comes with a bungee cord! ... show more

  • Well-built. Works great on wooden steps with overhang
Size: 330 Lb Capacity
I got the 330lb version. It is sturdy and well built. I don’t know if it can really handle 300+ pounds (have my doubts), but I used it to haul 75lb floor standing speakers up 14 carpeted steps and it worked great. My regular moving dolly was useless because the wheels got caught under the protruding overhang of each wooden step, stopping them dead in their tracks. I needed something that could safely go up the stairs without damaging my stairway. I had read other brands had difficulty in this situation because their wheels and “triangle axle” were too small to fully rotate over the overhang. Well, that just isn’t the case with this one. The wheel and axle are large enough to clear each step perfectly (see photo). It worked like a charm. I could not be happier. I am sure I will use it many times to move heavy items up and down my stairs. ... show more
