A solid build !

Shipping was great, and most importantly the way it was packaged, was unbelievable. Totally bullet proof. Well wasn't expecting anything less from a reputable company like GLA. Been away from planted tanks for few years now, and finally I'm ready to do it again. I set it up last night, and honestly comparing it to the regulators that I've had before, there is no comparison. It's a very solid unit and very consistent. I defiantly will have an updated review in the next few months. Thank you GLA.

Nice regulator

It's a nice quality regulator. I had to adjust the working pressure to 33 psi before fine tune started working. When I first tried less than 33 psi on accident - it wasn't working. GLA gave me badass scissors and tweezers with it - I'm in love with both the instrument and tools. Twizzers are much better that those I had in a dental office when I worked as a dentist for a while - very precise. I wish the hombre who was replying to my email would had his head in the right place - I asked for a chemical to bring my DI water back to normal - he told me he would add it to my order, but I never received the thing... And now, following the commandments given me by my Jewish grandma, it hurts my soul to think that I would have to make another order and pay 15 dollars for shipment just to get the can of that stuff... All-in-all the regulator was an excellent purchase - much better than some shoddy Chinese regulators. Buy the inline ceramic diffuser with it - to get the best result.
