Anyone in Toronto want some #ultrasonic cleaners? First picture is from the old Amazon listing in 2023 (not present now).

I have a 6L and a 10L model. Not used all that much. The heater packs on them are absolute garbage (better to boil water yourself and then add it for PCB cleaning), but the sonic function works just fine.

I think I have some fluid too, which I'll throw in if you have both units.

I'd like $100 for the pair, but am open to offers. Collection only.

Been experimenting with Navidrome (FOSS) media server for music (since it respects my id3 tags unlike Jellyfin) and while the linux setup takes a bit more effort, it seems to perform in the ways I need for my music.

I also switched to Ultrasonic android app which works fantastically both on my phone and in Android Auto - plus ts FOSS!!

Will need to try these out for a bit to validate my experience so far, but am optimistic.

I know the general rule in life is you get what you pay for, but does anybody have any experience with this cleaner? Seems too good to be true, over £300 cheaper than a HumminGuru. #vinyl #ultrasonic
