The DOW FilmTec Membranes were in perfect condition - in original manufacturer's packaging, Item shipped as promised - what's not to like? will keep them on file.

Marzena is driven like no other. I've been lucky to be on the right side of her intentions, and so have many fortunate clients. The energy for her work with Orphaworld comes from I don't know where. She has inspired myself and many others to join in that campaign to aid the forgotten orphans of TJ and even further south in Mexico.

Marzena is an extraordinary person with an amazing creativity and drive to achieve success in anything she puts her heart into. She is a problem solver and a go getter. Anyone will be lucky to have her as a business partner.

Highly recommend USA-RO to any purchasing director who's in a rush to get Hydranautics replacement membranes. Got the shipment within 3 days and not my standard 3 weeks, and paid 35% less than from my previous supplier. Great customer service as well! Can't beat that!

Wspaniały serwis, szybka przesyłka. Zamówiłam dla firmy wiele produktów marki Hydranautics i jesteśmy bardzo zadowoleni.

USA-RO was recommended to me as a local wholesaler in San Diego. Reluctant to switch suppliers, I gave it a try these guys have won me over. Super fast, knowledgeable, affordable. Also 10% from all my orders turns into a donation to purchase ro filters for orphaned kids. You can't go wrong with a good deed.
