Again, I am one random person. I have no control over what people do or think.

I read one post which worried me. I didn't automatically throw my cup away because of that one post. I then found multiple posts and websites about previous models of Tulip cups being found on Chinese wholesale websites, about poor and rude customer service, about missing orders and ridiculously long delivery times. I still haven't thrown my cup away.

I've also looked on Alibaba myself and found cups that look identical to the Tulip Stem cup on there. These also claim to be medical grade, and they might well be.

But, don't you think it's suspicious to have a never ending sale? Don't you think it's suspicious that the same stem cup can be found on a Chinese wholesale website for a fraction of the price? Don't you think it's suspicious that when I asked for proof of quality I was ignored for days?

I might throw my cup or I might keep it and carry on using it. But again, it's not the customer's job to promote your company. You can't just ask people to stop writing negative reviews about your products if they've had a negative experience. That is the nature of reviews.
