I made the same transition. My Ti just got...rough. the non-anodized threads really started to grind, even with lube and the thing ate O-rings as snacks. Picked up an Olight i3S after being very impressed with the specs for the price. Buttery smooth anodized square threads, not a battery crusher, and current regulated with great battery life. This thing has been tough as nails. It's ridden on my keychain for the better part of a year now and taken 2 or 3 trips through the washer and lived, although the ano is gone off of one end. Pocket clip is very strong but the crab claw attachment broke after only a week or two so don't use that. Only gripe is sometimes when it's really cold, it gets stuck on medium mode and I see you (jbrett14) also live in Michigan so that could be an issue. Although its only happened to me once. They may have fixed that issue since I bought it.
I received one of these brand new Olights as a warranty replacement for a failed iTP. Put it on my wife's key chain. It died within a year of very little use. This is when I decided to buy the Thrunites. Thus far, all 3 brands have proven to be a let down, to me.
