I have a Roland SPD::ONE Kick since before, and I absolutely love it. Thought I'd buy a passive device as backup, but I don't see any situation where I would do with this stomp box when used to the SPD::ONE Kick. So my recommendation is to get that device instead, it's easily worth 4 times the price.
Edit 2020-11-05: I have to edit my review after using this stompbox more, it's actually not that bad. I now use it connected to a Behringer X Air X18 digital mixer and then into Logic Pro X in my home studio to trigger "my foot beat" to improve the way to let Logic detect my tempo. For that it works great. For the price I can recommend it.
