All right Don't need a piano to fall on my head,... 3 yes, 2 no...*Edit, If D/O/Man is saying no too, that's 3/3
I watched the video you linked to, and I have to say this is what we used at my job (Electrician in an aluminum rolling mill).
(I say used because I retired from that job April 1 of this year.)
These things are very nice. The company bought all the tools, so I had no idea what they cost, I figured under a hundred but IDK, never priced them.
If you can afford this tool, I guess my answer would be yes.
If you really dont have a large tool budget, and this thing wont be used very often, id say No.
Now, my solid answer?
(Flipping coin).
Since you seem intent on getting this, and it seems you would use it more than I would (in my personal work), I have to give you a yes.
Go out young Jenn, spend like no tomorrow and ride with the wind!
