This works great.
OK - the quality isn't going to astound you but then again the price is very reasonable. I've used it to hold my tablet on my Ipad for approx 2 years now and it's never been a problem. It also includes a neat sized phone holder for those who need it.
Bottom line: It does what it says on the tin. For the price I didn't think it would last two years of gigging abuse but here it is still going strong.
Cheap and competent.
