Leaks when closed if it's not fully upright
Lauren· Review provided by hydroflask.com · November 21, 2024
Overall I like this lid enough to keep using it. Just wish it didn't leak when closed and on its side. I think it leaks because a bit of water gets trapped under the part that twists. I'm not sure how to prevent that, from a design perspective.

I trust the Hydro Flask brand. I won't buy off-brand lids. I'm worried about off-brand black plastic lids for Hydros that I find on Amazon. . . . a lot of cheap black plastic can contain toxic flame retardants from recycled electronics, so I don't want to buy any off-brand black plastic lids. Those manufacturers don't even say whether their lids are made from post-consumer content or not, so I worry the chances of those lids being made recycled electronics could be fairly high.

I trust Hydro Flask when they say they don't use recycled plastic because they've yet to find recycled black plastic that meets their high safety standards. I only want to buy HF-brand lids for this reason. But man, we need some better lids! Please put more effort into your designs.

I've been a loyal Hydro Flask customer for over ten years. I have many HF products. This is my feedback.
Everything about this is bad

*Don't buy this if you're a hiker, it's so heavy.
*There are 4! (Four)! pieces to be disassembled, cleaned, dried, and then reassembled.
*If you use it to drink anything other than water, you must clean it right away. Never leave it till later, because residue from the beverage will dry in aaaaallllll the crevices and indentations, and you'll need to use toothpicks or q-tips to get it out. And that stuff, if not completely removed, will cause odor and mildew that is impossible to get rid of. So, if you buy this, be prepared to completely disassemble and clean it every night.
*The four part cap must be put back together in precisely one way. Otherwise it will leak with every sip.
*Be careful when twisting the sip lid. You may turn it slightly too far and begin to unscrew the main cap, which causes spills.
*You need both hands to get it open to take a sip.

I'm anxiously waiting for the company to design a new lid that is lighter and has fewer moving parts. Until then I'm using my Contigo. I just push a little tab and pop! it opens one-handed!
[Rewarded Review] Leaky, leaky 4-piece tricky
Richelle S.· Review provided by hydroflask.com · September 14, 2024
I love having a handle on the lid. And before I used to get a spot of coffee on my nose if I lifted the cup too close to my face when drinking but that isn’t a feature in the new lid. But I hate the new “flex lid”. I’m on my third lid of this type. I have to take apart and reassemble 4 pieces every day now. I used to just toss the old one in the dishwasher. This one has such small pieces that they require special care to make sure they don’t end up on the heating element of the washer. The time it takes to clean is exponentially more. I could maybe get over that but it also leaks. And when it leaks it doesn’t come out of the top - it comes out of the sides and drips down my chest while I drink. I have stained two shirts already. That silicone seal gets twisted when you close the top and eventually fails. It’s infuriating. I bought a different brand. The HydroPEAK cup doesn’t stay as hot but at least it doesn’t steal my time and ruin my clothes.
Leaks, leaks leaks, all down my shirt!

I was so excited to try this easy sip n close lid, but it started leaking, soon after purchase. Liquids get trapped in between the seal when tipping to sip, and coffee dribbles out the seam, right down the front of my shirt when driving, every time I take a sip, once the leaking starts. I contacted company, and they promptly sent me another lid, but it too, has the same problem after a couple weeks.
I do clean it regularly, bit so bout have a dishwasher(me;). It's like the silicone holds onto any miniscule hard water deposit, any coffee, etc and it can no longer make a water tight seal. Really doesn't work. Please come up with a leak proof flip top lid, without all the seal, gasket issues. Great service, Bad product.
