Review: For best results increase the display size to 125% - 150% to use it comfortably. - Brilliant peice of tech. Incredibly responsive. Works great on a Raspberry Pi 5. Also a Steam Deck too. I am yet to try other devices. I did try a projector running Android TV. But it didn't work. Not sure as to why. Possibly due to the conflict of light perhaps. Easy to setup. Click in a few parts that are clearly labeled. Comes with some very strong adhesive strips. Great customer service, was told that this isn't a touch screen. Which I was well aware of but it's perfect for my use case. Using it as a Magic Mirror. Overall very happy. Highly recommended. It's expensive however you get what you pay for.
Review: Easy to set up and works really well. - It's not often I leave a 5 star review for a product because there's nearly always room for improvement, but not this. This frame works perfectly and is incredibly easy to set up The frame sections are marked to show which piece attached to which, and it also comes with a little screwdriver and double sided table already attached to the frame. On my windows 11 laptop, it was simply a case of switching it on and plugging the USB cable in and it worked straight away. I built an interactive smart table and uses a 5mm thick sheet of acrylic to cover the TV I used as the monitor and the touch accuracy was spot on. The instal manual came with a website link to a calibration tool which I did use, but the frame didn't really need it. Single taps, double tabs, swiping, pinch to zoom and mult touch points all work flawlessly. I never heard of this company or ever used an overlay frame like this so I was dubious about paying so much, but it really was well worth it. Highly recommend.

### ⭐⭐⭐⭐⭐ Easy to set up and works really well.

### ⭐⭐⭐⭐⭐ Great Product, Excellent Customer Service Excellent Communication,
*by -***- on 11 December 2019*

Great Product, had issue with the Screen not turning off in power save mode while the Overlay was plugged into USB. But the Customer Service Team at Chengying was EXCELLENT. Communication was consistent, polite and professional. The Technical IT Department got straight onto it, and the matter was resolved within days. Communication was by the normal Amazon messaging, standard email and WhatsApp. Chengying demonstrated that their Customer Service Infrastructure can be international and being in different countries and time zones are no issue. I also had to re-format my PC recently, but when I attached the "32inch 10 point multi-touch infrared touch frame, IR touch panel, infrared touch screen overlay" I had no issues, I have multiple screens and all turned off when left without any interaction after a period of time, and windows power saver mode work without any issue. This Product is a great alternative to purchasing a very expensive 32inch Touch Screen. From my experience, I was impressed with the Customer Service and the effort they went to resolve this minor issue that no longer exists. I have no issue with this Product, and meets my requirements and needs, the only issue I have is the double tap to open file, this is not has responsive when compared to the actual touch screens I have. Not sure if this is a simple Windows Pointing\Touch Screen Settings Feature I have missed in Control Panel. But I would give this IR Overlay Panel 8 out of 10 and 4 Stars. I would give the Customer Care and IT Technical Service at Chengying 10 out of 10 and 5 Stars. My Closing Conclusion… Product is great meets my needs and requirements, not quite at the same level has an actual Touch Screen, this is obviously to be expected. But if you do not wish to fork out lots of money for an actual Touch Screen, then I would most certainly recommend this item to anybody, value for money all the features you would expect from a touch screen. I have not got round yet to adding glass to my IR Overlay, this is recommended, and just may improve the overall performance. My experience with the Company\Business that are selling this product, not much I can say here 100% Excellent Customer Service, Great Communication, Communicated using Amazon Messaging, Email and WhatsApp, I can only therefore say from my own experience with Chengying. If you purchase an item from them you should get Guaranteed Satisfaction, Good Products and !00% Customer Care Service. Thank you Jenny and Sam for dealing with my problem and resolving my issue, thank you Chengying for having a delightful and professional workforce, were Countries and Distance Do Not Matter.
