The purchase process was smooth. I got in touch with one of the sales reps via the chat and then on the phone. The projector screen shipped almost immediately however, I had to wait for the projector for almost 2 weeks. Over all, I am impressed by the quality of the product and the image that it produces. One of the immediate items that popped up was on HDMI3 eARC port, my receiver was not receiving the input audio from the Android TV system and the input/screen refreshes every 30 sec or so thus pausing the externally sourced video (like Amazon Fire Stick). I raise a support ticket and waiting for an update from the seller. As long as I am on HDM1 or 2 or while on HDMI3, turn of the eARC on T1, no issues observed. Unless you plan to use external player like Fire Stick or Apple TV, this might be a deal breaker.
As it is already mentioned in lot of the reviews, the top right corner does have some focus issues but I felt it was negligible. The projector could have been a bit more luminous or brighter for my room (as it a basement with a window and bright ceiling lights) but when no ambient light present, the image is outstanding. The built in speaker is not bad but I would anyways not use it for theater experience. Still exploring the options on the device. The KeyStone setting needs some understanding for new bees like me. While I was not able to adjust the height exactly to get 120" screen but was able to get the screen to fill most of the screen, almost like up to 118 to 119". I do see some spilling of the screen in the darkest setting of the room but otherwise, no issues.
The experimental USB dongle provided works excellently with the system for shutting the VivdStorm roll down as soon as the T1 is shutdown. Liked it. Still working on setting up one remote for all the devices. Definitely need to tinker some settings for that to happen.
I wished there were more user defined profiles available to save for brighter room setting and a darker rooms setting. Otherwise, it is constant adjustment according to the ambient lighting. Still exploring the product.
