Never used them, but they say the right things on their web page . . . would be interesting to hear how they do if you use them.

I bought all mine through M&H (ordered through Year One with a discount coupon). The harness recieved would have worked fine, but there were a couple small details that were different. I documented the differences and sent it to M&H who offered to make the correction if I sent in my original harness.

Harness returned is outstanding !

Good luck whatever you decide.
