My name is Jun Yap and I am the Product Manager of Asian Cooking Hub Inc based in California, U.S.A.
This wiseholder product is really interesting and cool. I think this product is much better than the typical, boring kitchen trash bag holder that is currently available in the market. However, most household in USA will like to place the kitchen trash bag holder right under the kitchen counter top for example hanging it on the cabinet door or similar. Since your wiseholder doesn't have such feature, I wonder if you have any test result on the adhesive & hold strength of the suction cups on painted wood cabinet & door, especially with the trash bag full of weight, as the surface may not be as smooth as stainless steel sink or granite because the wood is painted.  Furthermore, maybe your company has a plan to offer a hang-over the door feature in the near future, please advise too.
Also, what is the maximum weight can the holder support?

Thank you very much for your time and attention. I'm looking forward to hearing from you.
Please let me know if you have any questions for me.

Best regards,
Jun
