We've got about 40 units of these in teh warhouse right now, and shippng within a week or so — air freight takes roughly 10-12 days, sea freight around 25-30 (check lead time if you're going surfce). It basically handles fields up to a thousand square meters pretty well, though for anything over that you'll want to let the engine cool every 45 minutes or so.
The engine's a 52cc air-cooled single cylinder, which basically means it's lighter than a water-cooled equivalent at 14kg — most buyers go with this for farm land or green spaces where you're not all day. 1.2L fuel tank gets you about 40-50 minutes continuous run time with the 25:1 mix, but don't run it straight gas or piston seizes.
SGS cert is nice to have, but honestly what matters more is we've been selling this same model for three years now, and the 8-month what it does — crank bearings, carburetor issues, that sort of thing. Also, one thing you won't see in the spec sheet: the blade adapter is steel, not aluminum, so it doesn't strip threads after a few months of heavy use.
Not ideal for very wet or marshy ground where you'd actually want a 4-stroke or electric — the air filter on this one clogs faster than I'd like with mud splatter. For dry brush and grass up to about 1.5 meters tall, though, it cuts faster than most competitors we've tested.
