"Had a fault with a RCD part in a consumer unit, so I call Screwfix spoke to a very helpful young lady, to see if I had to return the whole unit, she went to have a word with her manger she came back and told me they would send me a replacement. She took the order about 16.30 on the Wednesday I had the part by 12 noon on Thursday, cannot get much better service than that well done Screwfix and especially the young lady who took my call really helpful. As for the unit I got I cannot comment on yet as I have not fitted it yet, but I have used GB units before and this is the 1st time I have had a problem with them."
"reasonably priced compared with the alternatives available. seems solid and well made, has all the right numbers and markings for a genuine item. easy enough to fit ( if you don't know what your doing -get someone who does!) can't comment on the reliability or performance until it has been installed for a while"
"No complaints about this product. Bought it as a retro fit for a DB and it fitted with no problems and worked as it should. Good valve product. Can't comment on reliability as I've only recently purchased it."
