Test on two snowfalls (2 * 15cm): functional, with the exception of adjusting the clamping ferrules handle height. As long as the ground is flat, all is well, if there are asperities and the hanging plow, while the handles fold, so we rule again and greenhouse harder, and after three times (though it was not cold: -5 ° c) breaks clamping ring (too thin plastoc not reinforced).
Solution for the buyer: drill the tubes of the handle and put a pin to each tube. Obviously, after that, no question of back to store (or so we leave the tools), I'm fine, someone who has little storage space will be less enthusiastic ....
Summarizing: well suited to the city, to be tinkered to withstand off-road use. Considering the price and the apparent strength (apart from that I quoted), it's a good deal.
PS The Merdanium is a ferrous alloy from recycling WITHOUT mechanical strength, he roughly speaking the same strength as aluminum before the time when we recycled everything, but it is supposed to be of steel , hence the name: **** M + = ALUMINIUM Merdanium.
