Quick response

★★★★★Shelli F.

Ordered a gate prior to this one, UPS lost it on route. I reached out to Kidsy via email and they secured a refund from UPS. Was hesitant to order again, but I couldn't find the gate at a more reasonable price. 2nd order arrived with no issues. Gate is sturdy and the dog (Husky) hasn't gotten through it (he's an escape artist). Quick delivery from start to finish.

Best bottle warmer for breastmilk discussion
I love my Kiinde Kozii. It’s a water bath warmer and gentle on breastmilk since it doesn’t get too hot. It’s simple, clean. Only downside is it can be slow, but I just factor in the time. I’ve had mine for over a year, works great.

Bottle warmer conspiracy theory thread
I used the Kiinde Kozii and it was fine. Water bath, set it and forget it, didn't overheat. But for the price I wasn't super impressed. It's slow and my wife ended up using the microwave in a mug of water instead.

Kiinde bottle system review
I use the Kiinde system with the Kozii warmer and it's so convenient to warm directly in the bag. I've had my warmer for 8 months, no issues. The timer dial is simple and it beeps when done. It's not the fastest but it's safe for breastmilk.

Comparison of bottle warmers
I’ve had the Kiinde Kozii for 3 months. It worked great at first, then it stopped heating. I contacted Kiinde and they sent a replacement, no questions asked. When it works, it's gentle and easy. I hope the new one lasts longer.

Bottle warmer suggestions for new parents
I recommend the Kiinde Kozii if you’re using the Kiinde bags. It’s so easy to just pop the bag in and warm. No transferring milk. It’s also nice for my frozen stash. It does take a few minutes but I just turn it on before I change a diaper and it's ready.
