## Description

desertcart.com : Maymom Baby Bottle Thread Changer or Converter; Compatible with Spectra S1 S2 Pumps Wide Mouth Flanges to use Medela, Ameda, Lifefactory, Dr. Brown Narrow Neck Bottles : Baby

Review: Extras to save time on washing parts. - I honestly just bought these adapters on a whim, figuring extras couldn't hurt. Before these little guys, attaching the bottles felt like a balancing act doomed to end in a milky mess on the floor (yes, it happened). These thread changers twist right on, connect my Spectra flanges to my trusty old Medela bottles securely, and most importantly, no leaks. No sudden bottle detachment sending liquid gold flying. They just do the simple job they're supposed to do, which is a win. Pros: Super easy to screw on and off. Creates a tight, secure seal (no unexpected milk showers!). Lets you use different bottle types with your Spectra pump. Saved me from having to buy a whole new set of bottles. Cons: Just one more small piece to wash and keep track of in the pumping parts chaos. You do need to make sure you twist them on properly with the rubber piece, but it's not difficult.
Review: Perfect - Worked perfectly and fit just right !

## Features

- 2nd Generation bottle size changer; designed to avoid interfering with the duckbill, and easier screw on to both the widemouth flanges and the standard-sized bottles
- Allow Avent and Spectra S1 and Spectra S2 flanges to use with standard sized bottles like medela bottles, ameda bottles and original Dr. Brown Bottles (note will not fit wide mouth Dr. brown bottle) to replace the wide mouth spectra bottles.
- We recommend that you use a bottle-stand (such as ASIN B00PRPLRYQ) as well to reduce the tipping-over of the bottle.
- BPA free, dishwasher safe; FDA compliant for food contacts. Every batch is tested for safety. Test reports are online on Maymom's website for your reference.
- From a brand you can trust - Maymom and USA based customer service.
