About the lack of power of the installed motor, the exorbitant battery wear, the cheap production of plastic elements and the wobbly seat the battery cover have sichhier already missed a lot of critics of the product. I agree here completely, spare you and me more words about that. Most of all, I have annoyed me (except that I have the time, the part had to send back to elapse) at the crazy "instructions" are not worthy of the name. It is indeed written a countless languages, as well as tiny print that reading becomes tormenting. But mainly she explains nothing of what should declare an instruction manual. Would achieve no instruction as recommended scattered densities which setting for which grit would make sense or what pace you would have to go, or to what extent they should hold the device. Anyone who over-fertilized his grass and thus "burned" has know how important it is to follow the recommendations of the fertilizer manufacturers. And even on Wolf fertilizer products hand spreader is not listed! How do you as the right attitude guess good and to fertilize too much? I turned also to the service of the company Wolf with a request for settings and recommendations, but get of course after three months no response. The device is so, even if it would work well and longer not to use for fertilization of lawns (if necessary for spreading the sidewalks in winter). Addendum: Even now, after a whole year, the service of the company Wolf has not answered my question! Speaks for itself .....
