This item is a cheap piece of plastic that does not do a good job at all. It is a joke do not order this thing. Feels cheap in my hand.

difficult to secure a decent grip, unable to properly align fingers to grips. Thus causing discomfort.

Listen people, I see alot of reviews talking about the product is flimsy, doesn't work anything, etc, etc. Find your own grip on it vs what you see in the photo. Also, it may seem like it isn't working anything but TRUST ME, if you use this long (longer than 5 mins) you will feel it. I'm satisfied with mine so far.
