It is just the PID that is different I think. Personally I like the look of the $300 better but performance wise, they are all the same. This is according to Gimido.
So I actually just got my Gimido in the mail Wednesday.
I thought the sale going on was only through the new year so I jumped the gun and bought one on December 31st. If I had known the sale would still be going on now I would have bought the $300 Best Dabs. However, I settled on the $179...
Gotta have the inventor's sig on there :)
The one problem I have had in the last two months of daily use is my slip ring snapped when I dropped the whole bag on the hardwood. I feel like my friend's v.1 slip ring would have held up.
Other than that, the thing is a champ. She is precise...
