Would not bet on too much quality at this price... but maybe worth a try.
The better ones have a timer and intensity setting.
It's nice to let it work alone as the "buzzz" will drill your ears within ten minutes !
You'll get better resuts filling the tank with hot water (altough it will heat a bit during use),
then put a glass that contains acetone or trichlorethylen and drop your parts in it.
Do not mix ot all together !
You'll understand it's nice to have a tank as large as possible when using this method.
Macmark, it's to use AFTER polishing
