Amazing

I was really impressed with all the items I purchased. The capacitor discharge unit especially. It's well made, compact, and a doddle to connect up. It operates perfectly and charges up incredibly quickly too. So impressed I bought 4 more.

Easy and powerful

I make my own finescale track, so I'd had trouble getting those cheap Seep motors to throw all the way over. I'd been looking into getting a CDU for a while, but they were all either expensive, low powered, or self assembly, so when I saw this on show at the Doncaster Festival this weekend I snapped it up and had it installed the same night super easy - all my problems cured in one go! It's rated up to 35V, and I'd thought I'd need to use 24V - but actually, just 16VAC from my ancient Duette is absolutely fine. With 18.8mf of capacitance, this is just a beast!
