I've got a box of the free rough in's of the stuff right now in the shop. We haven't used them yet and are waiting for a good job to try them on. I like the idea of the system, the only problem I see is the device quality on the trim. Only time will tell if it catches on and if it is high enough quality to use.

I did see a competitor of mine that has 30+ trucks doing tract homes leaving their shop every day this morning had these sample packs on every truck. Looks like today was the day to try them. We'll see if they liked them. They are bottom feeders, so if it saves time, they'll use 'em.
