I've had 3 pairs repaired and saved a fortune on new glasses; however, each repair was FAR from the advertised entry price on their web-site and only confirmed once they'd 'examined' the glasses, i.e. once they were held to ransom!
It seems they charge £30 for the first stainless steel weld per pair of spectacles ... and that isn't particularly cheap!
If the work was beyond reproach, that would prove more acceptable; however, the weld to a visible part of the frame on one of my glasses was rather rough'n'ready, to be honest.
I might try eMailing them photos next time and obtaining a quote beforehand.
