No pinches or cuts on first run. It's awesome that it runs in the shower. Recharging is easy. Worth the price

  • Worked OK till it didn’t. Not magic. Not worth it
Color: Black
For the cost it’s a horrible product. I’ve owned other $29 trimmers that still work. I’ve had this a little over a year and it shows charged but won’t turn on. Looks like a common problem. Stay away from Manscaped IMO. Back to tried and true products. EDIT. I never set the travel lock. The device went all the way down. I charged it fully and it would not work. I had tried to push the on off three times quickly to see if the travel lock was on to no avail. I wrote the bad review. Before I decided to toss it while my other trimmer was charging I pushed the on off quickly about 30 times and it started up again. So there you go. It’s working. I’ll do a second edit if it crashes again. ... show more

  • Avoid at all costs
Color: Black
I don't understand how this product has such high reviews. I can only imagine it's being reviewed by people who have gone from using sand paper to this razor. By that comparison I'm sure it's great. But for those of us living in reality this thing is a huge waste of money. If I hadn't been stupid and thrown away the box before using it (who could guess it would be so awful) I'd get a refund immediately. The problem I have with this product is that it just doesn't do what it's supposed to do; cut hair. I've had a norelco shaver, not even intended for personal grooming, that I've used for over 20 years. I figured it was time to get something new since one of the guards is broken and I figured something new would work better. I got the lawn mower since I saw it had so many good reviews and I've been seeing manscaped products advertised often over the years and figured they'd have a good product. A bit pricey but I figured quality would be reflected in that price tag. I couldn't have been more wrong. The product is water proof so I thought, great, I can use it in the shower. Nope. Couldn't trim any hair that way at all. Or at least not in any reasonable amount unless I wanted to spend several hours and rub my skin raw going over the same spots hundreds of times. Just pathetic. So I thought maybe using it in the shower was a bad idea. Next night I tried it my usual way standing over the toilet. Nope. Slightly better than in the shower but that just means 90 passes over the same spot to get everything. So now it's back to the old trimmer that literally takes one to two swipes over an area to completely trim it. This product is absolutely pathetic and the company should be ashamed for putting their name on it. But then I guess that name doesn't mean much to me anymore so who cares what they put it on. The real sad thing is I bought their beard hedger too and it has the same problem only with beard hair. Can't believe how worthless these things are. Now I have to go write another review for this other POS I bought from them. Wish I hadn't thrown away those boxes... TL;DR Doesn't cut worth crap, save your money and get something that does what it is supposed to do. ... show more

This is my second time buying these. I had the first generation ones for years. These are great quality and shave without a problem. they charge quickly and the attachments are easy to connect. They cut very smoothly and the grips make them comfortable to hold . they are not as loud as other shavers. ... show more

  • A absolute great buy
Color: Black
This is a great product. It gets the job of basic hair removal done with ease. The light illuminates perfectly so you can see what you missed in every crevice. The battery life is outstanding! I stored this away for about 5 weeks before, pulled it out to use it urgently while in a time crunch thinking I would need to wait for it to charge but nope it was still holding a charge from weeks ago. It got the entire job done too!! Lightweight product great design, easy to hold and use and will not nik your skin!! I’m a woman and I love this product don’t get confused by the name lol. ... show more
