I am very happy with my experience. We had a shipping issue on my first order, and after working with PLUMBESTORE, they sent me another part ASAP. The part arrived very quickly and as described.
SanCO2 products are exemplary.but what was most impressive about my recent order was the superb service of PlumbEstore as provided by David. Great efficiency, accuracy, expertise and delivery were perfect. That is a true rarity in today's professional marketplace and deserves recognition & support.
