My greenhouses. It started when I sold a small property to move my greenhouses to a much larger property. At the time they were about 6000 sq ft. Greenhouses are built of galvanized steel and lots and lots of tek screws.You have to climb all over these structures to disassemble them. I had used Ryobi tools for years in my landscaping business for on going small projects, such as hanging sprinkler clocks, disassembling valves for repair, hanging Christmas lights and so forth.So I bought some more kits and batteries to start taking down theses buildings the extra batteries came in handy as the tools were getting a workout. The lanyards came in handy as you were in need of both hands as you climbed around the trusses at the roof line. Once down and moved to the new location they had to be put back up. This has taken much longer as we made the greenhouses much bigger then they were originally. We've dropped a few some survived we've worn out a few but we definitely got our monies worth from the tools. Fortunately for us you came out with the lithium ion batteries which makes the tool much lighter and last longer. I now over 18,000 Sq. Ft of greenhouses covered storage and work shop areas. Thanks for affordable quality tools They sure made my job easier. I now have a lot of tools and accessories. Pat King Owner KingZ Nurseries Inc. and Solutions Landscape Inc.
