I too am new to the marking gauge/wheel .... I have the LV micro adjust. I never used one before this one, and as soon as I took it out the package the first time it has worked fine. I looked around Highland the day I purchased mine to see if I could check out the titemark, but I didnt see it. Even still, something is gonna really have to aggravate me to make me put down the LV gauge for me to plop down almost a hundred bucks to replace a fully functional, well made tool that cost me only 40 dollars. So far, that hasnt that hasn't happened. It locks in place fine, feels good in my hand, and if it ever comes to me needing or finding convenience in having a second gauge, I will buy another LV ... and still have spent less for two of them versus one titemark.
Don't get me wrong, a well made tool should cost money, and I can certainly appreciate that.
I guess its one of things situations where you don't know how good something is till you try it for yourself. Who knows, I may try out a titemark one day and be blown away.... but as it is now... I am not blown away enough to say a hundred bucks is worth it to replace a really nice tool that works great.
I solved the rolling problem by drilling a small hole on the back vertical wall of my tool tray a little bigger than the rod. Just laying it in the tool tray annoyed me a bit.
