I really like this fabric shaver at 1st. After using it 4 or 5 times I'm not so sure about it. On the positive side, the battery does last a while %26 like others have mentioned it charges lightning fast. I do have to nte tho once it hits about 50% it is very weak, so weak it isn't very effective so you have to put it on charge. The super fast charging does help with this. Another issue I have found is you can't really lay your fabric flat %26 use it or all of the lint shavings accumulate in the head of the device "binding up" the blades, kind of a pain. I've also noticed that the tiny lint fibers seem to get stuck around the center where the blade section meets the motor and it is very difficult to remove them. That makes me wonder how long this motor will last with lint in it. The extra blades are a good thing but while emptying the unit %26 trying to get the lint from around the blades you have to be very careful, they are a little on the flimsy side. It has also snagged a hole in 2 spots on a blanket i have been working on, not happy about that at all. Will be looking for a better model.
