When I had them service my regulator, they outsourced the service to somebody else. They screwed up the service and the regulator had IP creep. When I went to pick up the regulator, I asked for a full tank to test my regulator before taking it with me, they said they don't have Tanks with air to use for the testing. I asked them how on God's earth do they manage to have a storefront without having a tank and a compressor, they just shrug their shoulders. I left the store without being able to test the regulator set. Eventually after few weeks I returned back to Libya and when I tested the regulator, it had an IP creep causing the second stage to leak air. I tested the second stage on another regulator and it was fine. Put a different Second stage on the first stage that was serviced by them and it was the same problem. All this while looking at my IP gauge seeing the pressure creep. I called them from Libya and told them about the problem including sending pictures of the IP. They said to ship it back to them in London. I shipped the regulator back to them in London with their agreement that they will refund the cost of shipping back to them. They eventually fixed the issue with the IP creep and sent it back to me but refused to refund the cost of shipping the regulator to them from Libya. They took advantage of me not being in the UK and far away in Libya to feel safe to renege on their word.
For me, their are just "traders" who just sell equipment but don't expect any service or anything beyond taking your money and giving you a box. They aren't honest, they certainly don't live up to their word.
