We used re-gassed spheres from Pleiades, so I thought I'd just post a "happy customer" message. Service was friendly and helpful, and (for personal customers only!) there's even an ace trampoline for my disabled toddler to bounce up and down on while the credit card payment went through.
Won't get as much refunded on the exchange spheres as I'd hoped, as the Xantia disgorged an eclectic collection of three spheres with indents (and thus spikes on the inside), one C5 sphere (!), one probably knackered sphere and three regassable spheres. But even without all 8 exchange refunds, it still works out a lot cheaper than new spheres.
And no, I have no commercial connection with Pleiades at all.
Cheers
Pete
