Better than I expected , only I prefer to use it without android set up and wireless . Only iPhone could be enough to connect directly
P
Very well made / robust item. The image is very sharp but also very contrasty - couldn’t find a way to make it look less HD and more filmic… The Google reliance is a bit of a pain for a Mac /ios user. The settings interface is clunky and unintuitive…
R
You fulfilled my order over 15 days ago and I am yet to receive my order. I moved my flight ticket just to get it because it was a gift for a friend and all of that fell flat. My correspondences haven't been treated with much empathy, just copy paste type responses and it is really sad. No offers were made to atleast compensate or ameliorate the inconveniences caused. I hope the product would be better than the experience I have had to endure.

Robust and sturdy, this gives excellent picture quality and the ability to adjust screen size etc. There was a slight problem with the first one but this firm were a delight to deal with and sent a new one out promptly, which has worked really well. Can stream content from my phone well - important as it does not have BBC or ITV capability. It does have Pluto and UK TV play. It also works well with lap top to play dads. Image is very good.
J
This is awesome.
One down point, it doesn't connect to BBC and Netflix is a bit faffy to manage.
Apart from that, the best projector.
