Genius idea

This is a great app. Everything I need in one place for fault codes also has Techinal numbers for all manufacturers so you don’t have to look for it. Just very handy app and saves time if you don’t have manual which is more often than not.

Over priced, this is just the mi’s

Sorry to say this, but nothing special here, very over priced for just the mi’s, with phone numbers and email addresses, I wouldn’t waste your money like I did, it’ll be cheaper, easier and quicker to google the boiler and GC number, and then view the mi’s in pdf. I feel like I’ve been mugged.
