    Great product but a replacement is needed

    Posted by jonathan cowles on Feb 13th 2017

    I bought this here 9 months or so ago and now my solenoid is going bad, so I contacted support and bang... We'll send you a new unit as you under the 1 yr warranty... Great company, thanks. Also as for not being standard refills, well that's wrong it's a standard fitting.

    Tank is refillable

    Posted by Glenn Lehigh on Oct 29th 2013

    I got very upset reading the other review about not being able to refill the tank, so much I almost stopped buying from this site. I did refill the tank at a local paintball store for $3.00. The tank though only can be used for 5 years, which goes for any tank, due to safety regulations. So far no complaints on entire set up, about a year old.

    $175 Disposable Kit

    Posted by HM on Apr 29th 2013

    It worked great for 2-3 weeks till it ran out. Unknown to me, the tank and regulator/solenoid connections are NOT USA spec, therefore it basically can't be filled again. (Do a google search and you'll find others with this problem.) After trying 2 LFS, 3 fire extinguisher places, 3 paintball places, and 3 welding/gas supply places I realized this kit a a $175 disposable kit. Aquariumplants wont accept a return, did not find a solution for me, and I have no way to use this thing. Disappointed with the product and VERY disappointed with Aquariumplants for not describing this upfront, not taking back a useless product, and not finding a viable solution.
