We were passing through Brest, the argon ran out, we arrived without any problems and changed the balloon, we paid on the spot, we accepted an overdue attestation, we paid for it on the spot, we were given a brand-new balloon. Everything is fast and efficient.
We looked at the boiler. The price is average, and the warranty is long-lasting. We also needed valves on the battery, as one had broken down. The price of valves is lower than on marketplaces.
