I just received mine today. Got them directly from Erik at the little 5SK/short game school today. Here my testimonial:
I have followed along how to install thru the website since I ordered the grips, but have never tried it before. Further, I've never installed any type of grip. I ordered an extra set of grips for my wife's clubs because A) she needs them, and B) if I'm gonna screw up at all while I'm learning this, I don't want to screw up on my clubs. :)
I think I started removing her old grips about 75-80 minutes ago ... and I've been finished installing them for at least 20 minutes now. They look great and it was soooooooo easy! Full disclosure: She only has 9 clubs and there was no tape underneath the old ones so that made the removal a little easier.
Can't wait to install mine! (Hopefully I'll have time tonight!)
