Exactly what I needed
Picked this up for my HVAC side jobs after getting tired of guessing where tiny leaks were. It shows me the problem spots fast and has already saved me a couple of callbacks, so I’d recommend it to anyone doing service work.
Great little helper
Found leaks in seconds that my old soap mix kept missing. Super happy with how clean and easy it is to use.
Works as promised
Had a couple mystery leaks on an old A/C line and the usual soap mix wasn’t cutting it. Gave this a try and the bubbles showed exactly where the leaks were in seconds, even on a warm line, so I could finally fix it and move on to the next job.
