Pro definitely describes this regulator
From packaging to instalation everything was full proof. The regulator was packaged in a box along with other items i ordered using form fitted foam. Nothing was damaged in transit do to this style of packing. They give you step by step instruction to install this regulator correctly that are easy to follow. I also got a couple of GLA tools with my order and the quality was outstanding. The real difference between GLA tools and Amazon tools are the quality and the comfort when using them.
I will never spend money on an Amazon regulator again. Spending a little more on a quality regulator will save you money in the long run as i have had cheaper regulators fail time and time again.
