Pros : I find almost "nothing" wrong with the Twister. With my severe back problems, this has been a God-send to me. I sold my old flat grinder after buying the Twister. It has far more and better features than any flat top grinder. The tilt position is perfect if your work bench is at the proper height. I have NO problem with my water pump. Once the pump is pumping water, it never stops flowing. I plan to buy a second Twister to set up with a 1/4 inch bit. Customer Service at Gryphon has been excellent. Three of our local Glass Art Guild Members own this grinder with only one minor complaint (see notes in Con box). I teach classes and recommend this grinder over all over grinders. I have used 5 or 6 different ones in the past. Quick-change bits are awesome to use. Great product from Gryphon.
|
Cons : With the three Guild Members who own and use the Twister, the only complaint has been that on large pieces of glass, water will run off into your lap, or on your shoes. Duh!
|
| Other Thoughts : Any owner of this grinder should read the directions and make note that they MUST watch the clear water tube to be certain that water is flowing properly before grinding. A simple "stop and restart" on the foot switch and the water flows great. I must constantly remind my students, because they are more intent on shaping glass than protecting equipment. I use a foot switch, but if a person is not going to watch the flow with each use, turn it on full-time, check the water flow and let it run. That way, you have water on the glass & grinder bit and you are not running a dry pump (which will burn up ANY pump). Gryphon Service Department bends over backward to take care of its customers. |

Pros : The good news is that it is fast & in the flat position it works great as long as you have the water filled to the max and a sponge in place. The quick change bits are also nice, they just slip on and off.
|
Cons : The bad news is that we have been through two of the water pumps & been on the phone with gryphon multiple times and still only had the water pumping through it for about the first week of use. The entire purpose of this grinder in my opinion is to reduce neck strain by tilting it, because when we grind, it is for hours at a time. Unless gryphon can make a better design that will actually provide a continuous flow of water (since you can't grind tilted without it) then this product is hardly worth it.

Pros : I have had this for two years - knock on wood - NO problems so far. I like the angled grinding surface, less neck strain when grinding for hours.
|
Cons : I don't have any cons.
|

| bad pump
|
|
Pros : Concept is great. easy to change bits. I like the bent bench.
|
Cons : I am on my second pump. This one is going bad. I am trying to rig my own pump up now. I will keep you posted
|
| Other Thoughts : Great idea bad engineering. Who tested this before going on the market? |
| angle is great
| 
|
Pros : The angle is great. The hose for a pump makes is easier to keep glass wet.
|
Cons : The grinding bits are hard to find, and the universal ones size on the shaft.
