fits great on my setup

This worked great for my BTA setup. Communication, service, shipping were all great as well.

Perfect for intended use and the abuse that outdoors activities delivers.

this device really helps with the Sawyer. I am very pleased with my purchase!!

Something you didn’t think you needed until you use it! Great little hack that now means one less ziplock bag and knowledge that it’s not going to leak in my pack!

Went camping for 4 days and this cap was a super useful addition to my hygiene kit! Dramatically reduces the amount of TP one might need to use, so there's less to bury, which is better for the land :) I do wish it was solid plastic and not 3D printed, but it's still a great product and I strongly recommend it.

The “everything + prefilter” are great! I tested them in my kitchen after backflushing my filter following a recent trip and there was no leak. I shook my filter hard to get rid of extra water in the filter and the pre-filter stayed in place. The shop owner answered my question quickly and shipped my items quickly. I’m pleased with my purchase and would highly recommend this shop. Thank you, Jeremy!

Installed it. Everything seems great. Will test it in the road soon

Great product, would definitely recommend!
