Ya I bought the 1.5 but they sent me v2 which honestly seems cheaper build than 1.5. screws were all random sizes, no instructions, parts did not even line up like the picture, etc. The description also mentions a sensor and a float switch, however this version seems to only have a float switch and the cheaped out on the sensor. Does yours have a sensor other than the float switch? There also appears to be no way to adjust the float switches height and my float switch even fully submerged does not float which makes it so it doesn't automatically trigger a roll progression. Contacted Fiji but I'm guessing that's going to be weeks of waiting for a response. I might just make a 3d printed adjustable float switch mount so I can adjust its height to get it tuned in.'
