Issues with the 3.8 have already been posted by customers on the other forum. I'm just relaying.
It would seem that for whatever reason there are some serious reliability issues with their design on the HC platform. I've seen over a dozen users post about their failures, half again with repeated, multiple failures. A handful have had their replacement units not even make it out of the driveway, let alone the others that failed again within 10 miles. For the price and the pain of lengthy downtime not a product I'd bet on at the moment.
