Hi Udon, Yes I use the Glass Mechanix kit. As in any kit, you'll probably find items that are using more often than others and things that you might want to change. Overall, have been satisified with my kits, but have purchased additional items from Delta and L/R over the past 4 or 5 months as well.
Thank you very much for your advise.... Since I am living in California, it's better off to go training in LV with GM. How much do they charge for the training program? I mean I don't need the package offer (hotel... flight.....), I just need the training sessions. Thank you for your input.
I have been using the GM power vac and the delta injectors for about a year now. If I had to choose only one it would be the Delta, it does an all around better job than the GM.
I also use the delta injector, after wasting my money on another brand injector its easy to use has very few parts .The thing I like the best is the positive feel you get while vacuum/pressure .
