I've tried several different types of wearable breast pumps, and all in all, you get what you pay for. The freemie was never strong enough suction being used as a double pump to fully empty me, and my Elvie pumps that I use at work are touch and go. I decided to give this one a try because its priced in a moderate range that is affordable for most people. This wearable breast pump is a single pump, meaning it can only pump one breast at a time. It comes with all of your standard parts and is comfortable to wear. I like that the milk capacity is roughly just over 8 oz, so if you are a heavy producer and easily fill the standard 4oz collection cups, this is a good option. Suction wise, its pretty good. It has several modes to help with expression.The only downside is that it can only do one side at a time, but if you are able, you can purchase 2 to get the job done. Its certainly more affordable than some of the super expensive options out there that aren't covered by insurance.
