Reviews

Safer than not filtering and reduces bottled water.

"Safer than not filtering and reduces buying bottled water. I haven’t tested all that it filters. I have used it sometimes at work when the water tastes funny, during boil water notices, and when hiking/backpacking. I do question on the purification part. I tested the water post filter with a TDS tester and the result is the same as tap water pre-filter. Not sure if that should be the case. I would still use and recommend the product with questionable waters. Especially if traveling in other countries."

Late delivery

"I am writing to formally complain about the late delivery of my order. According to the information provided at the time of purchase, my order was due to be delivered in 2 days. However, as of today, it has still not been delivered, and I have not received any satisfactory explanation or update regarding the delay. This delay has caused significant inconvenience, particularly as the delivery was time-sensitive. I chose your service based on the stated delivery timeframe, which unfortunately has not been met. I would appreciate an immediate update on the status of my order, including a confirmed delivery date. Additionally, I would like to know what steps you will take to address this issue, including any compensation or refund you deem appropriate given the circumstances. Please treat this matter as urgent. I look forward to your prompt response and a swift resolution. Yours faithfully, Pvail Singh"

Cap issue -- design flaw

"After reading a review where it was suggested that a camera lens tether would work to secure the cap, I bought one for my newly-purchased Grayl. But the tether didn't hold the cap and now I have a $74 item that I can't use. Glad to see one can purchase a replacement cap, but I resent having to pay the cost of the item plus shipping. As others have said, it's a serious design flaw in a high-priced item. Grayl should take responsibility: 1) Redesign the product so that the cap is secured. 2) Offer to replace the cap free of charge as a one-time thing if the cap gets lost."

Replacement cap

"It fits!!"

These caps came quickly, and

"These caps came quickly, and the color availability is great. The design is as unthoughtful as possible. Its a potential lifesaving device and the twist off cap, easily comes off just being bumped around in the pack. With no retention wire, my son lost his before ever using it once. Disappointing. Grayle purifiers are the best in the world, easily. I expect better design quality from this company."

Lost cap

"Loved the bottle…. But lost the cap as I could not fly unless is was loosened. A cap attachment would be a nice touch"

You need to design a

"You need to design a cap that stays attached to the lid. Overall a great product with a serious design flaw. If you lose that cap on the trail it’s big problem."

Q&A

Is there a cap with a tether attachment so they won't fall in the creek like mine did? Need one for the ultra press.: Good afternoon, the UltraPress does not have a replacement cap option that includes a tether. We have seen some customers use a camera lens tether as a substitute.
