Well i am a window cleaner, and sadly one of my customers had Safestyle do her patio doors. She had to get them changed no less than 12 times due to marks, finger prints and smudges in between the glass. This caused her months of stress and in the end the manager was very abusive towards her as she continually complained about the ongoing replacements also being of inferior quality. Believe me it was shocking just how many marks were in between the glass. I could see it myself first hand and often showed the customer so she didn't think that i had done a poor job. Yes, Safestyle are so safe that they cannot even put two pieces of glass together without permanent marks being visible between the glass. They have no safety and no style. Ever wondered why they have their BOGOF Buy One Get One Free offer? They have thousands of bad windows from their inability to put two pieces of glass together in a sterile environment that they boast so highly of their BOGOF offer! If you have decent eyesight, AVOID at all costs!! If you can't see very well go with SAFESTYLE!
