bad experience

Sent my reg In for service,got into the pool and a bubble in the high pressure hose.was told that it could happen anytime.benefit of the doubt.go to mozambique to dive and the mouth piece bolt comes loose on the way up to the surface at our safety stop..(After all the rubbers etc replaced and a report given of all good.)Was told never could it happen as all checked before it leaves the workshop.got my guage consol back and find that it was broken obviously from trying to get the pressure guage out.will be going to another supplier for sure.this all in a matter of 2 months.
