Can’t review when it’s only been in for a couple of weeks.

Have had this installed with my new machine, I haven’t fully tested it yet so can’t review now.

I'm not really able to give an opinion on this as it's one of those things that you'll never know if it's working or not. We're in a hard water area, so it seemed sensible to add it.

Honestly too soon to say how effective this is, but it is certainly an easy enough thing to connect and very unobtrusive.

Difficult to know how efficient a product like this is so just hoping that ‘something is better than nothing.’

was sold to me as a deal in post sales, but I don't see it and assume its doing a good job

Not had machine long enough to judge how effective it will be.

Initial muddle up with cost but was sorted easily and quickly by phone
