Jan. 5, 2022 update:We purchased a second of these in Jan 2021 as we’d damaged the USB port on the original purchase. Hubs went to charge v2 today and the USB port receiver popped out. We’ve now had it about 11 months. Sad as the rest of the device still is in great shape. Debating repurchasing or looking at another brand.August 2020 update: This little gadget is still going strong. Have taken it (with a 5-gal water bottle) camping with us twice now too. No issues keeping charged. We just try and remember to do so every two bottles or so. It’s obvious when it’s time as the flow (and sound) is much slower.In our attempt to minimize plastic usage (our city is no longer recycling any plastics above a 2), we decided to get the larger bottles. The city water is pretty gross. Brita replacement cartridges get old. And fridge water is meh and cold. We didn't want to deal with renting or purchasing a cooler as we prefer room temp water. So far we've gone through two 5-gallon bottles and haven't had to recharge. It's a little loud, but to be expected. Flow rate is better than expected too! Not sure about durability as we've only had it a couple of weeks. We DO place it directly over the bottle caps (Primo, Ozarka) after peeling off the paper label and opening/punching through the smaller hole in the cap. It's definitely sturdy once on there.
