Bought a replacement digitizer that had residue on the glass. This was not noticeable until it was installed against the black screen. The process involves peeling the protective screen layer and immediately placing the screen back on the iPad essentially sticking it in place. Unfortunately if there is an issue with dirt, residue etc from the manufacturer its too late unless you take the entire iPad apart again (1-2 hour process). Contacted support to have them fix the iPad as they had sold me a defective part. Their solution was to take the iPad apart and send back the screen for a full refund or nominal dollar refund. This is a joke, they should clearly provide a full refund for a defective part or repair it a their cost. I have no recourse but future customers should be aware of their lack of support for the quality of what is being sold. They clearly need to do a better job at customer support with quality control.
