Your take on this...Pros & Cons...think about purchasing one for now.

I didn't look too closely, but at $80/each, that seems high for something that goes slow and, for many applications, requires more than one.

It may be a good idea for other situations, but 1 floor jack and jack stands work just fine for my needs.

That's an interesting idea, which I'd never seen until you posted this. Considering how many times I've seen people crawl under a vehicle with just the micky mouse jack which comes with the vehicle, it could be worth having.
Then again, I also cringe when people use cinder blocks for jack stands.

A lot of modern cars don't have many safe jacking/jackstand points underneath. There's a few products with the same idea of letting you use one point to lift and hold the car up. None of them are cheap, but neither is damaging the underside of the car or having it fall on you. You'll want two, or four if you plan lift the car totally off the ground to work under it.

I'd check the collapsed height. It might be the picture but these look like they'd be too tall to get under many modern cars.

Cars?! This is a tractor forum? I'd assume OP wants it for his tractor.......

Oriented correctly on a flat solid surface a concrete block has quite an impressive compressive strength...which is compounded with a cap block...

Perhaps if you know what you are doing, line everything perfectly, and use a cap as you say; yet how many people actually do any of the above? Many people stand them on end, where they have that nice concave end for the frame to rest in. They crumble way too easily if you don't have them set just right. Why even take a chance when jack stands are do cheap?
(Or in my case, own a chain saw and plenty of trees.)

You are right...if not oriented correctly for the load they are very dangerous...

Nope. there's a faster easier way than this slow bottle jack

I bought one of those about 10 years ago, but I don't think it was quite that expensive at the time. I carry it in my truck because I don't trust the cheap OEM screw jacks to change a tire on the side of the road.
It is also handy in combination with my floor jack for rotating tires.
