The product is as described and the methodology of its function is well founded, it will take time to prove its effectiveness but I am sure it Wil prove beneficial.

So apparently if you install this little gadget it should prolong the life of your appliance. Didn't come with much in the way of an instruction but it seems straight forward enough to install.

I’ve no idea if this is working I’m just hoping it is.

So har so good still time to see how it will perform.

I got this as we live in a hard water area. Hopefully it will help with the limescale. Don't know how it works or if it is actually working so will keep fingers crossed, but worth a go as limescale is pretty bad here.

This sounds like a really good idea. It is invisible and I guess it is doing a job but I couldn't really review it as you don't see it working!

Didn't realise this was put on the machine whilst being connected

Hope it is doing it's job. Hard to tell if it is helping.
