I am really happy with macpress range
Started getting my crimp fittings from you guys and I am really happy with macpress range
Plumb Centre cant or wont compete and when I go there, they never have stock anyway!
Your deliveries have been usually next day and when there is a fitting to follow I get an email letting me know whenit will arrive (and it does!)
A proper breath of fresh air for a merchant
Thanks guys
