Yup, I have a small yard & they are perfect for it & make short work of sloped edges were a line trimmer would take a bit longer. They can mow over the brick edgeing were a wheel mower can't quite reach.
The thrust flattens long grass some & You use blade puck spacers to set the cut height. Allot of them are not set right or the blade mulched rocks & are very dull, but If set up right, they do work ok. Ive added cary handles, Bike bar grip & skateboard tape were you step to start on the small one. Also no safety shut off stuff, careful.. Every one Iv'e worked on so far has a muffler cooked deck & the engine mounts are compromised. The older fiberglass Toro 19 doesn't have this problem, mainley the plastic deck models with the tecumseh engine & the tight muffler arangement... I mended the smaller one with aluminum splints & jb weld, lined the deck with fiberglass cloth as well as adding thick felpro rubbercork gasket material around the lip of the deck & added 1/2" spacers on the engine mounts to space the muffler away & also washers between the impeller & the end of the crank, theres still enough keyway engagement & the crank bolt is extra long to acomadate the blade height spacer pucks. I can't deny they are novel...
