It's been one month that I use 2 alt300 with 6 meters of aluminum triangular structure sx292 and it throws.
Very easy to use, they take up little space either stored or installed which I think is important with a weight of 13 pounds / feet (with the entire structure is 59 kgs).
These are my first foot hoist and it's been awhile that I wanted and it's still a must.
The value for money is good because it amounts to 3 meters.
I hesitated but with ALT 400 + is 2 times more expensive and cumbersome and I do not regret that choice at all.
