Mine's very similar to
this one and I cant fault it. The one in the link is a few quid cheaper than when I bought it, my only advice would be to make sure you get bigger than you think you'll need as the volume is never accurate I thought 2L would be plenty big enough to do all calipers at once but its not, you need to do one at a time with that.
That said the standard of clean is perfect for cleaning calipers and/or carbs, fill the bath with a kettle of water and top it up with solution (depending on purpose) and you're gravy.
Stainless items come out gleaming but galvanised or unfinished stuff will need a tooth brush clean/whacking in the dishwasher afterwards.
To summarise If you value the time more than the money then its a bargain!
