Familiarity: I've used it once or twice and have initial impressions
Edelrid makes two Mega Jul Belay Kits: one with the Bruce Steel FG carabiner and one with the HMS Strike FG (aluminum) carabiner. The Mega Jul itself is manufactured from steel, so it can put some wear on aluminum carabiners. This listing here describes the Steel Kit. I ordered it, hoping to use the steel biner for gym wear and tear climbing while using another aluminum biner for outside. When it arrived, the kit I received was the aluminum biner kit.
Not a huge deal, but the only reason I ordered this kit was that the biner was expected to be steel. I don't need another aluminum biner, and I would've just ordered the Mega Jul alone.
