I don't have any experience with Sweeney, and limited experience with TH. I have an AquaPro. I serviced a friends TH last year after it was submerged in water for 2 days, all the way past the timer and battery. It was pretty easy to take completely apart and clean, and after a day of drying out and a new battery it worked just fine. It's still working now with no problems. My buddy probably has 1/2 dzn TH, and has had 0 problems with them.
