Chug Lid with Wide Mouth by Coldest

Nice product

Water flow is so smooth it makes drinking water addictive.

I had been a fan of the Coldest water bottles, but I'm pretty unhappy right now. The silicon/rubbery part in the chug lid needs replacing. I've already replaced the lid once on my water bottle. I asked Coldest Support for help and they said they do not sell the part. I don't even know what the exact name of the part is - silicon water bottle stopper/gasket? You can't just buy any gasket as some gaskets are made for things like cars, which is not food grade.Anyway, I've ordered a few different silicon water bottle stoppers, but none of them work as the underside of the stopper needs to be hollow and all the ones I got were not. I even took pictures of it and searched on the internet and I got lots of results, but nothing close to what Coldest uses for their lids.Without this part, the lid is NOT leakproof. They buy these from somewhere so why can't they tell us what that part is and where to get it? If this part fails, you have to buy a whole new lid. That is less expensive than another water bottle, but still, this part must cost even if I buy it, $1-3, but instead I need to pay $13 for a new lid.There have been other companies that have products instead of using using universal parts for things that are not proprietary, they'll use specialized parts designed for them by another manufacturer that cannot be readily come by, but that is not proprietary. So then you're forced to pay a lot more then simply replace that part.

The inside plastic seal already got mold growing on it. Have no way of replacing it unless I buy another lid.

Great, I feel I git what I paid for, a bit over priced I would say but nevertheless is a good product and arrive on time
