Anyone try these distributors?

I am planning to buy one, just to have on hand as a tool, for quick hassle-free trouble shooting I think they would make a great emergency backup solution too, or bring one along with a spare battery pack when you want to look at a potential project car that hasn't been started in a while, etc. Pop that baby in and clip a 12v and ground wire to it and va-room! (hopefully)

The car I recently bought has sat for years so I am chasing several issues at once and not quite sure what all is good or what may be worn out so this will come in very handy to work on tuning the engine back up one thing at a time.

My two cents at least. Can't go wrong for the price
