On the right hand side the lights are barely even visible they are so dim. Gunshots are loud but clear. The improvements I would make with these are just a few which you may not notice about how great everything is. Next take the long bolt, add a washer, then slide it through the frame, through both the holes on the resistance unit, then another washer and finally the nut. if you get my drift. My advice is to buy literally any other bikini trimmer. They are soft and warm and have a durable rubber sole that is great for indoor outdoor use. Aside from that completely unacceptable flaw the sound quality is meh at best. They wipe off very nicely with bleach wipes, have the anti-slip grip on the bottom(which has saved me multiple times! In regards to the fit I am a medium (purchased a medium) and it fit a bit big - this is the cut of this dress.
