Turns a Sigg bottle into a child's sip cup. We use this on the 0.3l bottle. With everything now being made in China out of plastic and painted with who knows what, it's nice to be able to have a durable, attractive alternative that's made in a country with safety standards higher than the U.S. Of course, if our 9 month old is left on his own, he'll spill a little water on himself, but I'd rather have a little water in his lap than a little lead in his tummy - any day, all day. 5 stars

I love this grip and my son loves it too. It turns his bottle into a sippy cup and I know it's safe. I love it! 5 stars

This handle makes my baby's Sigg water bottle very easy for him to hold. It seems like a well-fitting, well-made product. 5 stars

The handles aka "Sigg Gripps" on the Sigg baby and kids bottles made the bottles actually usable for our 11-month old! And we love the Sigg bottles!!! Without the grips, the bottles are too hard for children to hold - the shape is large around for a child's hands, unlike other narrower cups and sippys.

We had been using the Think Baby Trainer Sippy Cups (they have silicone sippy spouts) which were terrific and were the best step from bottles we could've asked for (the spouts on other BPA free products were a bit hard and too big a jump in transition). However, as new teeth came in and he started chewing on the silicone spouts (and Think Baby doesn't sell spouts by themselves - you have to buy an entire new Trainer Sippy cup - shameful) we were able to transition to more durable BPA free plastic. The Sigg bottles are terrific and the "Sigg Gripps" are wonderful - better than most handles on other trainers cups we've seen and tried! Easy on and off, easy clean, great shape, and easy for little ones to grasp and hold. The bottles are too easy to drop without them, so be sure to order them if you chose to get a Sigg for your child. 5 stars

Handles work as expected for the Sigg bottle. No complaints and they make my daughters Sigg easier to carry around and drink out of. 5 stars
