My experience - I rebuilt my original several times before I finally ordered the Rottendog board. The first one did not work so I returned it for a replacement - it also did not work. Told by the company "we got a bad batch". They refunded me and I ordered the Ingo board. That was >3 years ago (his first purple version) - never had an issue since. About a year ago I had him send me the color changing LEDS and swapped them for the cool white I initially ordered. Absolutely awesome product. Eliminates the "clock broken" error by somehow (I'm not an engineer) separating that function.
Well worth the cost and if you buy from him he will treat you like a customer for life and completely supports his products.
