I ordered a Treats CDI conversion kit, and they didn't have the V2 box in stock so they offered this instead. It takes a little more work to hook it up, you'll be cutting off most of the connectors and put the right kind on to connect to your other parts.
This one seems to be a lot more robust compared to the reviews for the V2. I've had it on for about a year now and have had no issues (I even ran a resistorless plug and boot for a while!)
