Pros : -Super quiet and very smooth operation (minimal vibration felt)
-Incredibly effective (takes only seconds to grind a piece vs minutes with my old grinder)
-Powerful (has amazing RPMs and highest HP motor for a glass grinder)
-Light bar is amazing and bright and you can see everything (gone is the tiny spotlight I had on my Studio Pro)
-Quick-Fit Bit holder is super slick and easy to use and bits last way longer than my old bits)
-You can use different, high-quality bits too, like the Brilliant bits
-Removable water tray (no more lugging the entire grinder over to the sink to drain and super easy to keep clean)
-Built-in splash guard (perfectly placed, works fabulously, keeps area around grinder clean, not solid so the glass can pass through it to get at all angles)
-No sponge and bulky sponge holder (Aqua Flow brush system works much, much better)
-Even more Pros, I just ran out of space!
Cons : NONE - it is sheer perfection.
Other Thoughts : If you are on the fence about spending the extra money to get The Grinder, it is well worth it! I wish I had bought this grinder from the start - my mind was blown by its exceptional function and quality. Nothing even comes close in comparison to the other glass grinders I have used. Grinding is so much more enjoyable and satisfying now. It is very versatile as well - the large working space is great for grinding big pieces and I love using the Mini G elevated platform and bits to grind out even the smallest of curves.
This grinder is worth every penny and with a 7 year warranty you can't go wrong. The company is fabulous too - Techniglass customer service is super helpful and backs their product 100% - had a Quick-fit bit holder that didn't quite stay in place on the shaft enough, so I called them and they immediately shipped out a new one at no charge.
