We have put up with quality problems with 3M touch screens for long enough and have decided not to sell their equipment. The financial and reputation cost caused by the failure of the 3M gear has been very high and while they have repaired the units under warranty, it’s just not with it to us. We deal only with small businesses which cannot afford to be without their gear for even a day. 3M don’t seem to get this and have been tardy in responding to what has now been a year long problem. The quality pitch 3M sold us on has not been backed up with experience.
