Review (1/5): Don't spend your money on this, you can DIY
This was a terrible ripoff. Sure it works and serves the purpose but I paid $20 for something that is literally worth less than $10. I was incredibly disappointed. It is literally a flat piece of plastic with 4 little stick on feet. I'm sure you could make one on your own for less than half the cost. I recommend you not purchase this product unless you have money to burn.
