I just got this in the mail and I am really pleased with both pieces. They feel professional quality, and it's a joy to play game with them. While waiting for the shipment to arrive, I had a couple questions about the product and they answered me right away. I'm going to order a second spinner for the bartop cabinet I am building.

I bought this to use with my Raspberry Pi mod in my Tempest Arcade1up cabinet. Works great!
Of not, the Spinner is not a drop in replacement. I designed an adapter for the previous hole to support the 28mm hole.

I am very happy for the quality vs price.

I have owned my X-Arcade controller from Gen 1 back in the days when it only had a PS2 support! I have always wanted to add a track ball and spinner particularly to play 2 of my favourite arcade games (720 and Marble Madness), I received these yesterday and what can I say but they are excellent! You can get the real feeling of the arcade machines simple tweaking the sensitivity in MAME. The spinner is super sensitive and needs the sensitivity dropping down to like 9 or 10 to give 720 the one rotation = 1 board spin feeling.

Haven't even install them into my X-Arcade yet - I literally put a hole in the box and mounted the spinner so I could get my 720 fix last night and the track ball just rested on the pad from the box and it was Marble Madness heaven! My son soon found out just how much fun MM is with the real controller!

So today, I will be taking my X-Arcade into my shed and turning it in the equivalent of a Tank Max version!

Price wise - these are a steal! It's $50 just for the X-Arcade Trackball (which for some reason comes with 4 buttons . . . a bit pointless when I have all buttons in my X-Arcade already!) and they don't sell a spinner! So $49 for this pair is fantastic!
