Drink Tops Tap and Seal Outdoor Drinking Glass Cover - Gently Suctions to Glasses to Keep Particles Out & Reduce Splashing - Perfect for Wine Glasses, Coffee & Tea Mugs, Beverage Glasses & More - 4pk

I have the black & grey set (no ventilation) and while the rubber smell is not obvious on their own, if you cover your glass of water (for example) for more than a few minutes, the rubber smell permeates the water and glass. It's quite worrisome and a bit scary. They look and feel fine otherwise.Update: I reached out to Customer Service through their website and they are extremely responsive, prompt and thorough. They're sending me a replacement that hopefully will not have the same issue; I will update here accordingly. So far, despite my initial product experience, I am very reassured by the quality of care and professionalism of their service and hope to have a better product experience to report upon soon.The smell has mostly dissipated or I've become used to it? I'm not sure. The ventilated version is probably best for avoiding smell if you are senstitive. The customer service was very genuinely reassuring, and I would feel comfortable ordering more products from them based simply on that merit.

Second set of these. I like that they are thin and flexible so they’re easy to take with us to outdoor events. People around us always comment on what a great idea these are (as they are fishing dead/drunk bugs out of their wine glass).

My husband and I love to enjoy a glass of wine on our back porch at the end of the day. Unfortunately, so do the bugs. These tops work wonderfully. The silicon outside kind of sticks to the glass to keep them in place, and the metal mesh part lets the wine breathe but keeps the critters out. The only better thing would be if they had some kind of sippy spot where you wouldn't have to remove them to drink the wine, but I'm not sure how that would work anyway. I'd buy these again, and probably will if we lose any of them.

I love this product. They are a perfect addition to a drink by the firepit. And, it kept some wayward ashes from getting into my cup. I do a lot of wine tastings with friends and I can see these coming in very handy for those occasions.

I have my coffee on my patio in the morning, and a glass of wine or tea in the afternoon and a wine at night. I have been using old Pringle lids as a cover for years, or a folded paper towel to keep flies and mosquitoes out, but these can blow off during wind or when using the fan in the summer. Top rack dishwasher safe. I ordered two different color sets. If you have company, the different colors can help you associate what glass belongs to who.

These are perfect for sharing a beverage outside with friends. We don't have to inspect our drink for bugs enjoying our beverage before we do! Fits a lot of different glasses. The colors makes it easy for guests to know which glass is theirs!

I wish I knew about this product years ago! I drink a lot of water so I carry a glass around with me all the time. Since we have cats, I tend to get cat hairs and other dust floating on the top of my water. I had been using a thin piece of plastic to cover my glass, but it always falls off. These silicone covers provide just enough suction to stay on even while walking around with the glass, and they come in a nice assortment of colors.

I love sitting outside drinking tea, but I hate bugs and flys buzzing and landing on my cup. These work wonders for beverage glasses and mugs. Wish I would have found these years ago. As I live on a farm and we have horses, which means yucky flies no matter how often we clean stalls. So now I am thrilled I can drink without worried about yuck from bugs in my drinks during summer months.
