I tested them and they have same thrust as 6030 gemfan with prop saver.
I use them on 48cm chuck glider (140g) with 1306 3100kv motor 2s and it goes vertical.
Also had a few hard landings on grass and haven`t broken it. It weights 4.6g with all the screws. I drilled the shaft to 3mm and it spins without any vibrations.

DON'T buy the replacement folding prop for the Mini Swift. These are the same thing, and you get twice the gear for the same price.

As expected these are cheap copies of the small Graupner folding props, I'm not complaining though because of the huge price difference ;-)
My only issue is that the spinners are made of a very thin plastic: out of the six units I received, two spinners were bent out of shape in such a way they are unusable.
@HobbyKing: use a slightly bit thicker plastic on those spinners and you have a winning product for your 5-8-10 grams brushless motors!

Nice Little Motor that will power my Nuri XXS. With a tiny screwdriver and a (light) hammer its easy to convert it to a pusher! If you want to do so also, have a look at the pins which hold the blades: one hoel is a bit thinner than the opposite. This one is the side where you have to push out the pin for conversion. Spinner runs not too precise - I expect some vibrations Thats why only 4 stars.
