I have an Ibasso T4 amp with about 50-75 hrs of usage that is heavily scratched on one side. The amp works perfectly and comes with box and charger. The only reason that is so worn is because I used to use it at the gym and rest it on the machines. The exterior of the t4 is very prone to scratching.
It's a great little amp but I do not use it anymore ever since I bought my iphone last November.
