Snug Sip Universal Water and Juice Silicone Bottle Toppers - Soft Spout Conversion Caps with Spill Proof Valves - Silicone Bottle Covers for Travel - Includes 4 Bottle Toppers and 4 Cases

My favorite invention. Love to keep these in my bag for my kids if we forget their water bottles we can transform any water bottle into a kid friend option! The seal is great and the kids and use it themselves without spilling. Traveled with these and they’re universal. They fit perfectly in a purse or a backpack or just leave it in your car for emergencies. Whoever invented these is a genius because the design is great. Good value for money and you can take them anywhere!

We love these things. They're so handy to leave in the diaper bag in case we need to add a spout to a regular bottle. So far we haven't found anything it doesn't fit onto, it's pretty universal. Yes, it will come off if you pull on it or if your kid manipulates it enough. Or if you squeeze the bottle too hard. But it's more versatile than a straw, and better for the environment. We love this for traveling.

This is exactly what it said it was! It fits multiple size bottles, and unlike other products of similar use, these ones are easy to get on/off, to clean, and to drink from.

Boon has a really good product line and I recommend them overall. This universal spout is perfect for toddlers whom aren’t quite ready for open drinks. I tested it in a few bottles I had available and found it is pretty close to universal. This spout fit perfectly on wide mouth bottles (Gatorade, Cirkul, etc.) and found no leaking. I did find it helpful to remove the entire bottle lid including the plastic ring at the bottom. I also found that the spout fits okay-ish on standard narrow mouth bottles (water, soda, etc.) and minimal to zero leakage. With the narrow mouth bottles I did find that the spout has a less tight fit, minimal leakage, etc. I did rate this product as a 4 star vs 5 for two reasons: 1. I would have personally preferred to see two separate sizes one for narrow and one for wide mouth bottle. This why the narrow mouth bottles aren’t getting the short end of the stick. Due to the fact that this is utilized by kids minimizing leakage and creating a tight secure fit is really important. 2. I would have personally preferred to purchase this item based on one individual single color versus a packet of four different colors. This set combo included two girl colors and two boy colors. Some kids are extremely picky about colors, which is very common and normal. This leads into an issue where wasted product is occurring. Due to this it does significantly decrease the cost value rating.

LOVE, LOVE, LOVE these! I am seriously considering dumping our bottle collection and buying several of these instead! My toddler loves them; they are spill free and mess free. They are easy to install and such great solid quality! They are so easy to clean and fit in my purse, his diaper bag, my pocket. I can literally take them with us wherever, whenever. I no longer need to worry about dragging around an assortment of bottles for my sons variety of beverages. If there was ever a must have product for a mom of littles, it is these!
