Excerpt: I bought this model to provide a little stability to my frequently-used Manfrotto 680B monopod. I bought it not even realizing that the legs can fold up so that they slip into the shaft of the monopod when the tripod isn't needed.
Pros: Easy To Use, Fits Well, Improves Tripod Function, Solid/Sturdy
Excerpt: These legs fold up and store inside a monopod. I use the 681 monopod with the folding base to support an additional strobe. When using this setup with a camera it is easier to stabilize while holding it. While the legs are in storage, they tend to rattle, I will have to think of a way to quiet them.
Excerpt: I received the 678 folding base for my 680 monopod today. The first problem was removing the original rubber foot without scratching or marking the monopod leg. I used a small vise with protected jaws.
Excerpt: Easy to install on my monopod by following the instructions that came with the unit. The hardest thing was removing the rubber tip on the monopod itself but a pair of channel locks did the trick.
Excerpt: The base is perfect if you want to stand the monopod up. It is very sturdy. Nice how you can fold the feet up into it so it will fit in a small tripod bag, Only negitive thing about it's heavy because it is made of steel. Maybe they could make it out of aluminum?
