Peter,
That's a very legitimate concern, tell us more?
The Noco, like CSC, deserves a fair shake though.
The packaging is grade A+ imho, instructions too, and the battery itself exudes quality.
I have not used the smart genius charger I got from them, but I can say both my RX3 and RX4 crank/start instantly now.
Your choice of course, but thought I'd share the links.
