It's a specialty tool. Some jobs it's a pleasure to use but on most jobs it's not worth it.
Pro's: 30min to 1hr dry times no matter what, it looks cool and different, you can give the customer a view of the massive river going through the clear tube and talk up your dry times.
Cons:It takes a little getting used to, it doesn't clean as well as a proper wand, it uses mega water, it catches hairballs in the clear tube, it's solution slots get clogged, it's plastic and breaks, it can drop grease one and awhile, the swirls are hard to rake out and require attention before the dry, bouncy on cgd and can leave permanent distortion with mega heat, slower than a wand, the skids get torn up on tack strip, can't clean corners, I'm probably forgetting some.
