Pros
Very versatile for any craft. Very cool with lights inside and transparent glasses on the outside. I made a birdfeeder out of mine, by drilling holes in the bottom part of the block using a diamond hole saw and a container of water, decorated the outside with glass and copper wire and won Best Project for Any Skill Level as well as Diamond Tech Crafts Favorite in the recent Ring of Fire Artists Challenge. This was the first time I ever used this product and it ROCKS!

Cons
None I LOVE THIS PRODUCT!!!

Other Thoughts
A round shape with a flat bottom would be cool, something similar to a gold fish bowl.

Pros
Grind with confidence. Not one risk of chipped glass with these bits. I will only use standard bits for really tough glass from now on.

Cons
No cons

Other Thoughts

Pros
nice shape

Cons
would like to be able to make sides higher but was scared the glass would melt over the edge of mold and crack dish when it cooled

Other Thoughts

Pros
This pack was a good variety of colors and all beautiful; four pieces were broken in shipment and Delphi had no problem shipping four pieces - no questions! I love Delphi!!!!

Cons
no cons, sorry.

Other Thoughts
Might want to revisit packing.

Pros
I have used this flux for 10 years. If you use the right flux brush, it goes on smooth and stays on.

Cons
I think you have to use brushes with real hair....the very inexpensive brushes have plastic brush tips.

Other Thoughts

Pros
Easy to glue, nice smooth edges, a solid choice.

Cons
Pricey.

Other Thoughts
I've tried others, but come back to these because of their quality.

Pros
Plenty of power and handles all my grinding needs. All in one saves space.

Cons
Its a pain to flip around to use the other grinding surface.

Other Thoughts

Pros
Love the different shapes. I can make pendants and earrings all at the same time!

Cons
It's addictive :)

Other Thoughts

Pros
This is the best little tool. The instructions are easy to understand and the device is made very durable- much nicer than I even imagined. Sturdy enough to hold up to years of use.

Cons
I just wished it was cheaper so I could have bought it sooner.

Other Thoughts
Notice: You now get instructions with the item!!!
