Green T Mini S - Professional Bonsai Shoin Turntable with Sucker

The top of this turntable is awesome. But..I was given the suction cup version for Christmas. I've tried to secure it to several surfaces. My work table is stainless steel which you'd think it would stick fine to. Unfortunately, it comes loose after 15-20 minutes. Which makes it pretty much useless. I wrote the manufacturer to see if I could buy just the clap portion and convert it. They tried to sell me an adapter type contraption that cost almost as much as the turntable in the first place. Which tells me they had trouble with the suction cup.
