Review on 🌡️ Triple Insulated Stainless Steel Tumbler by Albor by Ben Balas

I have written to this company twice and after 2 weeks still have not heard anything. I only bought 2 of these to pour my coffee. I think the lid won't hold because of the heat. When I put a cold drink in, the lid stays in place and there is a small leak through the lid. Now over 3 weeks, 2 emails to the company and still no reply.
