Yes, there is a test report here:

Personally, I really like this projector. It is very important to set the keystone correctly, otherwise everything is blurred. First we have to adjust the menu "Advanced / V-Keystone" until it is straight, and only then we have to use the Keystone button and do it 2-3 times. Then the picture will be tip-top and sharp on the whole size.
The brightness is good I think, at least enough to let the light from outside in, but not directly sunlight. It can also be used with the room light, we still see the picture, but the dark colours are not so good. It is better to turn off the light.
For me it was no problem to order, it came very quickly.
