They work great. What more can you say?
Make sure you adjust your time for constant agitation.

I use them to develop 4x5.
Pros:
Nice, even, development and allows you to easily control development time for each sheet. They use a small amount of developer per sheet. Also is nice that most of the process is "lights-on".
Cons:
They are a bit fiddly. You still need another mechanism for fixing and washing. They don't work well for highly diluted developers. Although the kit comes with 6 tubes, developing 4 sheets at a time is about the maximum I would try to take on at once.
Overall, I like the system and will probably continue to use them.

Dear John,
They're OK. I vastly prefer a modified Paterson Orbital, http://www.rogerandfrances.com/photoschool/ps how orbital.html

View camera mag, ran an article on BTZS a long time ago. You can make your own with some PVC pipe and end caps, or just roll the PVC tubes in 3 trays (Dev, stop and fix).

I'm really happy with them - have been able to develop 6 sheets at a time without any problems.
The major benefits for me are the small amount of developer required, and I only need to have the lights off when loading the film in the tubes, and when swapping the caps for the developer. All agitation done in room light, and stop bath and fixer in dim safelight.
For fixer and wash, I transfer the sheets to film holders and use open-top Yankee tanks.
I haven't had any problems with uneven development or scratches on the negs. Some folks make their own from PVC tubes, but the quality of these is really nice and it has been worth the cost for me.

I don't use the 4x5s but I do use and love the 8x10s.
Since I am starting to work with 11x14 I may have to build a set of tubes for that. 🙂
