Great silicone, but the carabineer is a joke. They break after very few openings. DO NOT trust the carabineer, and buy good ones.

I would give these a zero star. They are so stiff u can barely fit them over a standard small cap water bottle. Won't be using

Great price, quality. Love the variety in colors. Easy to use. Enjoy using one every day.

They come in handy while I'm working in the hot desert sun. Seem to hold bottles fine.

These work well on Walmart / Sam's Club 20 oz water bottles

Excellent execution of this device. Silicone rubber keeper rocks!

perfect fit

excellent product

Often working from heights in the summer and needed a safe way to keep water handy. Wish there was range in size, fits a standard water bottle lid but not a sports drink.

I love these when out and about and not wanting to carry a backpack or large handbag for drinks

Exactly what I needed to attach my water bottles to my carryon. It’s sturdy and hold the bottle well.Set comes in four, hence can be divided amongst four people or given as gifts.

UPDATE--FOUND A BETTER PRODUCTI recently found a better product -- "Bottle Buckle Clip Hanging Buckle Portable Water Bottle Ring Holder" (also available under other names). Attaches direct to belts up to 1 1/2" wide. The bottles can be easily removed for a drink without detaching from your belt. "Installing" (and de-installing, or changing) water bottles is easy.--- The only shortcoming is that some of the very cheapest grocery store water bottles have slightly smaller necks and do not have a sufficiently large collar just below the cap. A couple of rubber bands around the bottle neck provide a solution -- an annoying inelegant solution --- but it works. You may be able to find a thick o-ring which would work better than rubber bands. Alternatively, you can save a bottle with a wide collar, and refill the bottle as needed, but that partly defeats the purpose.---------------ORIGINAL REVIEW> Works well with small (up to ~12oz) "grocery store" water bottles with a 1" diameter neck (with a flared collar above the neck and below the cap). Won't work with thicker bottle necks, such as larger bottles, or even small Gatorade bottles. Doesn't work as well with some of the very cheapest water bottles which have essentially no collar below the cap.> No matter how hard the bottle gets bumped or jarred, a > Takes up little space in your luggage, in your car glove compartment, or even in a pocket or purse "just in case" you need a carrier.> It can be difficult to attach the cheapest grocery-store water bottles to the holder because they crush under the necessarily tight grip required. Of course, you can save a more rigid bottle and refill it from thinner bottles, but that kinda defeats the whole purpose -- there are better reusable bottle/carrier combinations for sale on Amazon. And again, they would probably stretch if left permanently on a water bottle --- and then not hold as well.> Carabineer easily attaches to a belt loop (or a purse, etc., I presume)> You CANNOT easily de-install a bottle from the carrier to take a quick drink -- instead, you have to take the carrier and water bottle together off your belt, but that's easy.> UNFORTUNATELY, the bottle flops around uncomfortably if you walk briskly. It's a little better if you use it on a belt loop farther back -- but then it is harder to reach.> Alternative 1 -- You can thread your belt through the carabineer, for a more stable "ride", but if your belt is thick and/or rigid, you may have to unbuckle your belt to slide off the carrier and water bottle for a drink.> Alternative 2 -- The carrier comes with a keyring (for no obvious reason), but if you attach the carrier to your belt with a keyring holder (such as "Police Zak Tool ZT55 Tactical Stealth Black Extreme Duty Key Ring Holder") (and don't use the carabineer), your water bottle will not flop around quite as much. The water bottle and carrier easily lifts out to take a quick drink, and easily slips back in place on the key ring holder when you are done.> Although I'm not completely thrilled with this carrier, I've purchased five or six alternatives, and found none which work with "grocery store" water bottles as well as does this carrier.
