They didnt squeeze my head, so no headache or ear aches. Picked size 6. Its a lightweight than the normal projector so I can carry where ever I go especially on school or somewhere. It seems as if they have made formulary improvements. This Cimetech wireless mouse is genuinely silent in use with no audible ‘click’. Buy this Kimo ratchet and complete your car repair in half the time. I think for the size the could have made that a sub and still manage to fot a mid and a pair of tweeters. One better than the other. I installed it on my sons 18" bike and extended it to the longest possible length. Ive been using this forever but my last batch smells different.
