iNerdz Parts strives to supply quality parts so technicians and customers are confident during repairs. We’ve been there; we know what it is like to open a box of screens worth thousands of dollars, just to find a pile of junk. So we check all of our screens by hand to ensure you don’t run into problems during repairs. However, if for some reason you do ever encounter a defective part from us, we have a lifetime warranty that guarantees immediate replacement.
