Refillable gas systems

Surfer

Are Safefill and gaslow the only two on the market at present that do refillable systems?  We were going to go with Safefill as their website indicated that there were two agents near us.

On checking the first agent closed up shop last year and the other about 8 months ago.  Safefill were notified several months ago, but failed to update their website. This makes one wonder how many other Safefill agents have closed shop and it has not been
updated on their website.

So maybe time to notify the Advertising Standards Burea that they have misleading information on their website.
