Waste of money
I bought this to replace my old one but after a couple of days it just never changes colour from blue to green so I put my old one back in the tank as well using same liquid solution & it changes colour no problem so now I am back to using my old one and the new one is in the bin where it belongs.

Does the job.
It does the job and it is easy to use. There are cheaper alternatives but this has a quality look and feel

Not very good
Had to replace this after 2 days as it started to leak CO2 from the main body seal
