I've got the kit and I like it...does the job and gives me a place to store my tuning supplies.
I added 3 Swix brushes (the one they supply is useless)
Use the wax for hot scrapes (bought Hertel Super Hot Sauce for main wax)
I've used the edge tuner, gummy stone, and file to Tune/Detune
Overall, it's a nice and organized convenience purchase. If I had to do it over again...I'd put my money towards a better iron and buy all the little things separate.
