What the Machinists Using G-Wizard Say |
Your product already paid for itself the first time I used it.
G-Wizard does a better job than lots of packages including OneCNC and Mastercam.
I installed the Gwizard, Its a cool tool!
Great job! This is the all in one kind of solution that I was looking for.
That is one slick looking program.
Thanks & keep up the good work.
It looks great. I like the layout and it's pretty easy to navigate. Again, great job.
Thanks for the nice tool! This is handy to say the least.
Looks like this is exactly the program I've been looking for!
I used a similar program but yours has more options, and overall a better look!
Nice application, great work!
Wow this thing is TOO COOL! It's a really really slick program
You've literally taken all the annoying little calculations and figured them out from every single angle, just brilliant.
Every time I run your app, I find something new. |
Awesome tool Bob.

Bob, thanks for the software i really like it!!
Very nice package, sure make speeds and feeds much easier.
I love what you have done, it has been a good resource for me.

G-Wizard is great!
I just surfed thru some of the pages and all I can say is FANTASTIC. Thanks again for all the hard work.
It is the single most useful thing I have added to my shop since the mill! I go to G-wizard first for all the feeds, speeds, tapping info and I also used the geometry page!
It will be a valuable asset for many shops.
The program is very nice, and will be a real boon, to both beginners and experienced folk. |
