EIO Glass Kids Cup

EIO Glass Kids Cup

EIO Glass Kids Cup (8oz). Totally BPA free. Unmatched Versatility. Environmentally Friendly. Starting with genuine, durable canning jars, EIO’s unique design offers the only spill-resistant toddler training cup designed for convenience and health benefits. Available in: Orange, Green, or Purple. The Kids Cup is a spout-free, valve-free cup made without BPA, Phthalates and PVC, and is designed to transition young children properly from bottles to real glass dinnerware. Sippy cup spouts and valves necessitate a bottle-like sucking motion, but EIO’s unique cap promotes correct sipping, quickly and with less mess! Give them confidence. Give yourself convenience. EIO is a one of kind kids cup. Our cap and sleeve fit on virtually any 8oz canning jar. The sleeve is easy to remove and can be left on the cup for washing. How’s that for convenience? We lost the valve… so you won’t! EIO’s cap is specifically designed without small parts, like the easy-to-lose valve. According to the ADA’s recommendations for better dental development, children over the age of one should drink from a cup without a valve (* From The Journal of the American Dental Association, Vol. 135, No 3, 387). Spouts can also be detrimental, as they tend to become chew toys. EIO encourages a healthy, natural transition to cups. Clearly, it’s EIO for years to come. Our modern design appeals to kids of all ages and our versatility allows you to use the jar without the cap as your child learns new skills. The sleeve offers a flashy style and grippy surface no matter how old you are! Never throw them away. That’s great news for our environment!

Perhaps not ideal for children with noses

I realize no product will work for everyone, but I honestly believe that this didn’t work for us due to its design and not my daughter’s preference. A minor issue is the girth of the jar, which seems a little much for a small toddler to handle comfortably, although the silicone grip helps some. The main problem though, is the lid. The opening is recessed, while the rest of the lid is flush with the top. Which means, tip the cup enough to dribble (and I do mean dribble, my final complaint is that the air vent is ineffective so the water doesn’t flow fast enough) and the flush portion of the lid bumps into the child’s nose. Which means she has to tip her head way back in order to avoid squashing her little nose while waiting for water to drip into her mouth. I payed the (in my opinion, ridiculous) price for this cup because I thought it would provide a more natural transition to an open cup, but watching my daughter try to use it showed me that’s not the case.In the end we settled for plastic and bought the ThinkBaby straw cup, which she has used successfully from eight months old. The straw cup helped her develop great water drinking habits, and at two years old she drinks from her little Libbey and Ikea juice glasses every day. Apparently a transitional cup wasn’t necessary.Two stars for the concept, and silicone grip.

Glass is not covered with rubber on the bottom

FYI we had to return this. we have tile in our kitchen and were looking for a glass cup surrounded by rubber. this is NOT!

Yep, it leaks like everyone says

I bought this because it is the only glass cup of it’s type out there right now (that I know of). I hoped I would get lucky and not experience the leaks other reviewers experienced, but this was not the case. Liquid pools along the threads of the plastic top and dribbles down the side, all over your fingers. Annoying. Before returning it, my husband suggested we put a rubber washer in it to see if it helped. So I guess I’ll try that, though they really should fix this design flaw. Wish more companies would attempt to make stuff out of materials other than plastic. We need some competition to get some better products out there.

love it

I got the cup for my 16 month old independent little girl.She loves it since day one, we use it at the table, and it took her 1 week to figure out how to drink without speeling water, and then we took of the top, and since she has been drinking from it and love it.Don t get it if you want a sippy cup, this is not it, it s cup!

Great learning cup!

This is a great cup for learning to transition from sippy to regular cup. It has a small hole so your kiddo can learn to control quantity. And if they tip the cup straight back, you won’t have a huge spill on your hands. Also love that it’s mostly glass (I try to stay away from plastic as much as possible). Would highly recommend.

My son loves this cup. However the plastic top did break very easily when it tipped over. It created a sharp edge so we’re no longer able to use it. I was definitely bummed by this because we were so ready for our son to transition away from traditional sippy cups. But overall we’re happy with it and would be willing to give it another shot!

these cups are terrible. They are heavy and extremely bulky. Very difficult for our toddler to handle. Don’t like them at all!

Great product and idea!

I love the idea of using an actual GLASS cup for my child. Teaches them coordination and helps them understand how to work with the weight of an actual glass. Rubber sides not only help keep the glass from breaking if it hits the ground (although I’m sure it would break if it fell from a great distance), but also helps little hands grip the sides. My son is still a bit too young for the product, but my niece used it OFTEN when visiting our house. I have not yet tried the sleeve and lid with other canning jars, although I’ve heard the lid does not seal properly when using some brands.

Godd Idea, But Lacks Durability

I, like many others, LOVE the idea of this cup. We use the Safe Sippy or the Life Factory sippy cups since neither are plastic, but my son is 20 months and is ready for the next step in sippy cups.He loves this, but sadly there is no way to prevent the liquid from literally pouring out of the top of the cup if he turns it upside down or tilts it. So if it tips over, you’ve got just as big of a spill as if you were just using a regular glass. Definitely not a good idea for the car!The biggest drawback is the durability.Because it’s so easy to spill with this cup, we were practicing outside and he dropped it on the sidewalk ONE TIME and it cracked in like 4 places – even with the silicon sleeve.I’ve had two Life Factory sippers that have been dropped a zillion times and they’ve never cracked. Still, I like the idea behind this cup and I’m planning to buy another one. I think it’s just better for a slightly older kid. Or maybe my son just loves dumping this out.

I do not like plastic so I got these for my son. They are awesome! Simple design, durable and easy to use. My son likes them too 🙂

No leaking problems here!

We have been using this for 7 months now, and I always gets washed in the dishwasher. NO LEAKING around the lid for us, as some others have describes. I always make sure the lid is screwed on tight.For those wondering, this is not meant to be a "leak-proof" cup. It is similar to the tupperware children’s cups with lids, only this one is more like an edge to drink from, verses a spout.I do wish they weren’t so expensive. But I haven’t found anything to compete.

great for learning to drink from a cup

I tried one of these because my daughter really wants to drink from a cup, but is still kind of spilling more than she drinks. Although this cup definitely spills when she drinks from it, it is definitely less that with a traditional cup, and she loves to drink from it.

Great Idea

My toddler learned to drink from a cup without using this cup very often. He couldn’t figure out how to turn this cup so the opening was at front. The sides all look alike from the outside so you have to look for the hole.
