Good way to keep using bottles you already have
I think this is well worth the money if you already have a lot of bottles and are looking for an easy way to transfer a young toddler to a straw cup. It fit perfectly with the existing bottle tops and is leak proof. The weighted straw works well.

Fantastic sippy cup adapter
Works great baby loves them they are easy to clean and easy to use on her already favorite bottles. 100% would recommend to anyone. Zero leaking unless pushing on the sippy part while upside down, super durable.
Grace –
Works for my toddler!
Tried a couple of straw bottles, but my toddler kept spitting the milk out. This is the only straw that works for him. Fairly easy to clean and fits the Philips natural flow bottles.
Jennipher –
It’s a great straw cup kit and has slowly become my preferred straw cup to use for my kid
Ok, here’s a long review but I hope it helpsCons…1. Inner straw is just a thin as the munchkin straw2. Cleaning brush is garbage (I use another brands brush to clean these)3. I feel these are slightly over priced when you take into consideration its only the straw pieces and handle4. I don’t really feel like this is a con but people should know… This cup will OCCASIONALLY leak just like any other straw cup. The pressure builds up and milk will slowly push up through the valve. I don’t own a single cup that doesn’t do this.It’s time for the Pros!1. EASIER to clean!! The narrow inner straw can detach from the wider mouth portion of the straw. This feature alone make this cup superior to the munchkin cup. Additionally it’s pieces are easy to clean unlike the Dr. Brown straw cups that have extra holes and valves. Technically the thin inner straw on the Advent cups are 3 pieces but I dont seperate the smaller parts for cleaning every time.2. The valve on the outer straw is really close to the top of the straw. My son likes to flick his straws, splattering milk everywhere! The valve being at the top limits the splatter.3. Outer straw is wide and looks like it’s more comfortable in his mouth over the narrowness of a Dr. Brown straw cup.4. I CUT the straw down to fit my smaller Advent bottles. I like that the length can be customized to fit my preferred bottle size. Of course you have to cut it just right to make it work. I’m not sure if the brand would recommend this due to possible error but it allows the straw to float right at the bottom like other straw cup brands.5. I’m like the idea of converting my old bottles into straw cups to help reduce plastic waste. Like I mentioned above I do wish these were slightly cheaper seeing how the company is only proving a handle and straw.Things I’m indifferent about…1. I don’t like or dislike the handle. They are bulky so sometimes I don’t add them if I’m taking this cup in a diaper bag. But they are way easier to use over silicone handles.2. Sometimes the straw nipple is hard to get in the ring… it takes 3 extra seconds of effort but it’s really no big deal as long as I slow down and focus.

love these. resourceful
fits the regular phillips advent glass bottles that i got and i love it i dont have to buy a new sippy cup for a while. good price for 2. the weight keeps the straw down and its easy to clean. also bought a silicone sleeve for the glass bottles and 10/10 recommend both products
Leah –
Good idea, quality is questionable
They are really great idea and easy to clean BUT they do leak out of the straw if left on its side. The quality of the handles is pretty cheap as well. I was putting a set of handles on the cup and 2 tabs broke off.

Saves money and reduces waste!
These turn your Philip Avent bottles into straw sippy cups! You donât have to buy cups and can repurpose all those bottles. My baby seemed to transition well to these because they looked so similar to her regular bottles. And the weighted straws are so helpful.My only âcomplaintâ is they are a pain to clean, but all straw sippy cups are so thatâs not a complaint to this specific product. It does come with a little cleaning brush and that works great.
Scott Johnson –
Great for converting bottles to straws
My son was phasing out the bottle but I rather him drink out of a straw in a glass bottle. This conversion kit was perfect. Super easy to clean with the brush they send you. It doesnât leak and fit the bottles perfectly. These are the best!
