The HPA starter kit is an amazing deal and I loved how convenient it was to get everything required with one purchase. However I have to tank this review score due to my experience with the Redline Mini SFR Air Regulator. The Redline reg has given me nothing but issues. Out of the box it didn’t work and had pressure creep. I sent it in to them and they fixed it, awesome customer service. However, less than 2mo later and only having used it 2-3 times the same issue presents again. And this time when I reached out to Redline there was complete radio silence and they were no help. All in all, this starter kit is amazing but just make sure to order anything but the Redline regulator.
