Review on 📽️ PTVDISPLAY Pocket Portable Mini Projector, Full HD 1080P Pico Bluetooth Video WiFi DLP Projector with Android Support, HDMI USB TF Card Connectivity, Wireless Home Projector by Brian Garrett

I am computer IT professional for 17 years in hardware and software. I don't normally post negative reviews on Revain, I just want to share my opinion and hope it helps the seller/seller/manufacturer. I will describe as briefly as possible: Hardware problem: 1. The device gets a little warm (not hot), I can understand that this is because the projector's LED consumes a lot of power.2. A slow processor (lags, freezes) can be either hw or sw.3. The remote control is made of flimsy plastic and the battery cover doesn't even hold up. it is easy to remove. Short RF range, you had to point right next to the projector to control it.4. Power Consumption: The battery runs out very quickly, around 35 minutes during setup, testing some YouTube video clips. Battery charging is too slow, about 1% every 6 minutes5. OS freezes when connected to USB devices (Maybe the processor works harder when USB is connected) Software issue: 1. The most disappointing app is "Eshare". The pen icon got stuck in the top right corner of the screen the whole time during mirroring (no option to disable). Very laggy, buggy in every application (perhaps performance and operating system) 3. It is not possible to install many useful applications from GooglePlay, there is a limitation in this device. In any case, I had to contact Revain to return this product. But I appreciate the body stylist's looks and Revain's excellent customer service. deleted this review and offered me $40 cashback but they lied.
