I reviewed here on SlotRacer back in April. I liked it - and the app has been updated since then with more features.

Yes, you plug it in to a current powerbase (with the rectangular plugs & sockets) to replace a controller. You can use a Spark Plug in one lane and a standard controller in the other. You can also plug them into the old ARC One powerbase and have both Spark Plug and the ARC app running - but you'd need three smart devices for that to work for two Smart Plugs and ARC.

Thank you Woodcaote might splash out on a pair of them.
