Mitigated
As a Sim Racing fan, I have mixed feelings!
So yes it looks good on Youtube videos, but in reality it's... blurry! In racing for example, when I look at the rope of a corner spread over 2 screens, I infinitely prefer my screen edges (2cm) to two large blurred bands (7cm), which make me lose precision and break my experience in general.
When I had a single screen, I thought that the screen edges would ruin my experience and that this kit would be the solution to make me jump to the triple screen. In reality it was the opposite: I removed the kit and in less than one turn I had forgotten about the screen edges and found sharpness in the corners, a double surprise in the end!
This kit has at least the merit of having made me take the plunge towards the triple screen (and especially to appreciate it as it is)!
I adapted this kit to three 32" screens (using one of the various tricks available on the net), too bad this kit is only designed for screens up to 27".
