I am satisfied with this product, article that meets my need (after years of struggling to use an electric trimmer with the extension cord to pull every 5m, I put 2 hours to do it all with this 45 min - 1 hour max , perfect). Pros: Easy to start - Easy to install - small reservoir capacity equivalent but 1 hour of work (for only a cobelet of mlande 25cl) - Strong powerful - Wire Bodine high quality, easy to roll through the system automatic exit - Eats (compared to what is available commercially for the same hardware brand). The -: I have a field that requires use of 45 min - 1 hour, so anticipate buying a strap to maintain, I'm not a big sports: o), with equal force to this weighs 8,5kg fast heavy - Plan to be properly empowered (especially in the legs> pants + boots, and eye level) because of the power hand we must protect, small stones and other objects fly vites. I hope this will serve you.
