QuoteThank you so much for the technical support given for both my Gunson Mk2 Gas Tester and Professional Gastester. Also thankyou for the spares sent. All units are working perfectly. This is the best after sales service I have received from any tool company and will be purchasing more Gunson products in the future. - John W from BuckinghamshireQuote
