I bought this two months ago, as I don't like it being too slippery on the back of smartphones so I bought this to make the back more comfortable in the hand. It's very cheap and I bought 4 and now only have one left, because it's made of plastic so it peels off easily, like tape.😊 1$ i got 4 so it's very cheap and i will buy again later if the remaining one runs out, could last a long time if i add a softcase.😁
