I also bought a set of ratcheting wrenches a while ago. The logic behind was that they would be useful to tighten -or loosen- bolts or nuts in those confined places where you don't have much turning angle and you keep turning and re-placing the wrench on the head 10 times in order to make a full turn of the nut or bolt.
The two or three occassions I could have needed, I couldn't use them. In one of them, the wrench head -with all the ratcheting mechanism- was too big and couldn't fit the nut in the confined space. In other ocassion, the allowed turning angle was so small that it was not enough to cross to the next tooth in the ratchet, if you catch my drift, so I was turning the wrench back and forth and it moved but the nut didn't.
And in another occassion, once the nut got loosened, it was so loose that the wrench was turning it back and forth, being the ratchet mechanism tighter than the nut.
When the nut or bolt is exposed, I just use my socket and ratchet. or regular wrench.
