Worth the subscription

I was looking for a cheaper alternative to bottled drinks, so I tried Hydrology's monthly subscription for the mango flavored tablets. The 20% savings on the subscription made it a really good deal. The tablets are convenient and make tap water much more enjoyable. It felt like good value for the money, especially with the recurring discount. Shipping was standard, about 7 days. I'm happy with this purchase.

Nice tablets, slow shipping

I ordered the discovery pack to try a few flavors. The red fruit and peach tablets were really tasty and dissolved well in my water bottle. I liked that they're sugar-free. The stainless steel bottle I got is solid and keeps water cool. My main gripe was the shipping time; it took over 10 days to arrive, which felt a bit long. Overall, good products, but they could improve delivery speed.

Love my new bottle!

I got the grapefruit flavored tablets and a reusable bottle and I absolutely love them! The tablets give my water such a refreshing taste, it's so much better than plain water. The bottle is super stylish and feels really durable. I take it everywhere with me now! I'm definitely going to get more flavors soon and probably another bottle for my partner!

Good citrus flavor

Bought lemon flavored tablets. They dissolved fast. Water tasted good. Shipping was okay, took about a week to get here. No issues.

Hydration made easy

Just got my first order from Hydrology, a pack of mint tablets and an insulated bottle. I'm usually bad at drinking enough water, but these tablets really help. The mint isn't too strong, just a nice hint. The bottle feels really sturdy and keeps my water cold all day, which is awesome. It was super easy to order online, and everything came well-packaged. Happy with how it all turned out.

Are there any current coupon codes for first-time buyers? Or a referral program to get a discount?

M Matt Rivera 2 weeks ago
Check some influencer pages on Instagram, they often have codes for 10-15% off your first order. I got one that way.

R Robert 2 weeks ago
Pretty sure they have a welcome code if you sign up for their newsletter. And there's definitely a referral thing, if you know someone who already uses it they can send you a link.

thinking about signing up for the monthly subscription, but what if I don't like a flavor or need to skip a month? is it easy to change or cancel?

D Danielle Moore 4 weeks ago
Yep, it's pretty straightforward. I changed my flavors last month without any hassle. You can pause or cancel anytime, I think it's directly in your account settings.

Super easy to manage. I've paused mine a couple of times when I had too many tablets stockpiled. No issues at all.

How do these compare to Waterdrop? Been using Waterdrop for a while but thinking about trying Hydrology.

S Sofia T. 3 days ago
I've tried both. Hydrology's flavors are more subtle and less sweet, which I prefer. Waterdrop feels a bit more intense to me. Give the discovery pack a go, you might like the change.

Hydrology doesn't have that weird aftertaste some Waterdrop flavors can have, at least for me. And the bottles are really nice quality.

hey, anyone tried these flavor tablets? thinking about getting a discovery pack but wonder if they taste artificial or actually good.

P Paul Brown 3 weeks ago
I just got mine last week, they're surprisingly good. not super strong like some other brands, but definitely not artificial. the red berry one is my favorite so far.

Yeah, I use them daily. No sugar which is great. I started with the lemon and mint, both are pretty decent. If you're into subtle flavors, you'll like 'em.

Does anyone know if the stainless steel bottles are dishwasher safe? Or is it hand wash only?

D Donna G. 1 week ago
I think they say hand wash for the bottles to keep them nice, especially the insulated ones. The infuser parts are probably fine in the dishwasher though.

S Sarah Evans 1 week ago
Yeah, I always hand wash my Hydrology bottle just to be safe. Don't wanna mess up the finish.
