only issue would be the price. the product was 128 landed, and might not seem like a lot but i feel the quality of the device itself is some what cheap. the extension for the back piece does the job, however it is hard to coordinated and the plastic feels cheap, and struggled to hold in to place when moving too fast. have used it for over a week straight now and overall happy but think improvements on the cost to get it under 100 dollars and a stronger extension could be a winner for the product.
