I always heard good things about the cirkul bottles and I was excited to start using mine because I wanted to start drinking more water, but my experience has left me very disappointed. I received my first order and the first couple of flavor cartridges I used were inconsistent and ran out of flavor after 3 refills of water (they claim it last 6 bottle refills set on 4) so I just figured I received a bad batch or something so I emailed them and they said it might be because of one of the gaskets on my lid and gave me a mile long list of things to try and offered me 3 free cartridges for my troubles. Well it turns out all the cartridges run out between 2 to 4 refills of water and they are all very inconsistent, I tried everything to fix it, I even bought a couple new lids. Every time I contacted customer support about it, they gave me the same mile long list of things to try that didn’t help anything. Another thing I didn’t like was the shipping takes way too long, even with expedited shipping, that you have to pay extra for, still takes over a week. My last order, they didn’t send half my items and I had to message them 3 different times over a course of a week before they emailed me back, and they pretty much ignored everything I said in the previous emails. I think the only reason they finally emailed me back was because I filed a complaint with the BBB. I would not recommend this product because of the inconsistency of the flavor cartridges and because of the horrible customer support.
