I've been using this for about a year, but I no longer need it, so I'm selling it. It was quite powerful and easy to use. It's a suction cup type (adhesive gel + lever-type suction cup), so it can be used on various doors without scratching them. You can also raise and lower it with one touch using your foot when your hands are full! ■ Quantity: 1 ■ Size: 83 x 270 ■ Thickness: 60 ■ Materials: Main body: ABS resin, steel; Suction cup: Thermoplastic polyurethane, synthetic rubber; Leg cap: Synthetic rubber ■ Remarks: Compatible range: 12cm from the floor KQDS1201 Size (approx.): 83 x 270 x 60mm - Color: Black - Material: Plastic - Type: Door stopper Thank you for looking.
