Review on Enhance Interactivity and Accessibility with Chengying Points Multi Touch Infrared Touch Commercial Door Products by Paul Dobson

I don't usually write such bad reviews. This product stands out as one of the most disappointing purchases I've ever made. The calibration at the bottom of the screen is off by an inch on a 27" monitor. The toolbar in macOS and Windows is untouchable. Calibration couldn't fix it. The calibration is variable. It's okay in the center and most sides, but impossible near the bottom and top of the screen. It's practically useless. The website also advertises a driver available from Apple. According to Apple Support, Apple does not have a driver for touch screens. The only compatible driver I could find is from Touch-Base. It's a good software package, but it'll cost you $110. I tried this touchscreen on two different computers with 27 inch monitors. One for Asus Art Pro and one for Dell. Both of them had the same problems. I do not recommend this product. I have sent it back to Revain for a refund.
