DEWINNER2 pcs 8'' Vacuum Suction Cup with Pressure Gauge, Heavy Duty Vacuum Suction Cup with Handle Lifter, Glass Suction Lifter for Granite, Tile, Glass Lifting, Black

Fantastic, using them on slightly textured porcelain outdoor floor tiles, and they really grip, I didn’t think they would, these tiles are 600x900x19 so no lightweight.Also used them to pull an integrated washing machine out of its hole.These are quality, strong, well made, and grip like hell you physically cannot pull them off once you have got the pressure up into the green.

Best purchase - lifts large 60X90 porcelain tiles comfortably!

I have just used these suction cups to lift 80 large format (900x600) 20mm porcelain slabs in place on a new patio on my own. The slabs have a R11 slip-resistant surface and so I was sceptical about their ability to lift them safely. However, the suction cups worked perfectly with no issues at all. Just keep an eye on the pressure gauges and make sure they are in the green segment before lifting. Also keep all contact surfaces clean. My initial reason for buying these was to make it easier for my back when lifting but the bonuses are you can position the slabs without trapping your fingers when laying and place the slabs exactly where you want them before tapping them down plus use them for fine adjustments. If you decide a slab hasn’t gone down correctly you can also just pump the suction cups up again and lift the slab up; this takes considerable force but they hold! You do need to keep an eye on the gauges at all times as given the R11 surface the pressure does drop. I would say approx 2 minutes until they go into the red section, but that’s plenty of time to lift, place in position, tap down and final positioning. These suction cups are fantastic and I thoroughly recommend them.

Very good product!! Using 50 times except maybe 5 or 6 slips where the suction loses grip but over all very good.

Bought these to handle 600x900mm large porcelain slabs. Invaluable tool - and the pressure gauges are useful to see if they are safe to pick up. My porcelain slabs have a rough texture on top - but these had no problem maintaining suction and lifting them up after sprinkling a little water on the suction cups. The pressure guages let you see if any air is being slowly let out before you pick them up.

Suction:Suction cup failed when lifting 1200x600 porcelain tile causing the tile to break.Not fit for purpose, product returned

Excellent choice. Holds double glazed inserts perfectly. Make sure you set the vacuum

Work just as they should. Happy with this value for money purchase and as always, great delivery service from Amazon. Two of use lifted a large heavy shower tray into position without any dramas.
