"Needed to lift some very heavy laminated and toughened safety glass to form a frameless julliett balcony. Due to the height involved had to work from the inside of patio doors hanging out of the opening. Therefore we needed a reliable device to manouvre the glass units. Had thought about buying similar units on ebay but the Screwfix ones were just marginally more expensive. I had my reservations but the triple units worked a treat. No idea how they would stand up to prolonged use but were well worth the money I paid just to get this one job completed."
"Very effective suction lifter. Take care to press the suckers against the smooth surface as you close the cam (adding a little water helps too), otherwise they don't always stick. However, once they're on, they don't move, and lifting and manoeuvring heavy panels or glass sheets becomes far easier and safer."
