I just dislike how the terminals on the S1 are pushed so far out, it even appears that they are wider than the inside diameter of the basket! That is a big deal breaker for me because it would be overly difficult to cut the diameter big enough to accommodate the terminals while still sealing with the screw holes and basket inside diameter. The only way around it would be to cut little divots for the terminals to slide through, which still won't totally eliminate the issue!
However, the S2 doesn't look too bad. Love the cone, and the inclusion of direct leads and push terminals. Wish the zipties were cut a little closer, would suit my OCD a little better haha.
