Picked this up for an arcade cabinet I recently bought. The cabinet is a Taito Vewlix clone with a 32inch LCD screen with 720P resolution. Truth be told I wasn't expecting much, inline SLGs at this price point are generally a waste of time so lets just try it and see was the initial mindset I went in with.
Connecting it up is as easy as you would expect. VGA out from your game device/board > SLG > VGA to monitor and it just works, so far so good and no unpleasant surprises. Build quality is good but the board itself is lacking any real functionality, of the configurations I tried I only noticed two distinct settings; very fine or very thick scanlines. Luckily, the fine scanline setting is truly outstanding for what it is. I can honestly say for the purpose of cleaning up the image, it does an extremely good job of it. The scanlines can be seen if you look closely but they are not blatantly visible when you move back a few feet.
I'd initially considered using an OSSC as I already own one, but after using this i'd honestly say it isn't worth it. Sure it doesn't upscale or line double, at this price point that was never going to be an option. But what it does do is give your image a distinctly cleaner and nicely filtered image, emulating what you would expect from a consumer CRT.
Would have rated 5 stars but due to the lack of any real funtionality and the horrendous thick scanline setting i'd say 4 is about right.
