Query: Built in Obsolescence

Bought all 3 tools, storage unit & 3 batts for $200 or so. I was initially satisfied with the tradeoff - convenience and weight vs. power and endurance, but like all tools, time has been the true test. The 18v batteries are supposed to last 150-200 charges, but all 3 batteries died in less than 50 each (and probably closer to 40 charges). Replacement batteries are expensive and would only compound the unit cost (good money after bad). Even though I'm used to Craftsman tools being handed down across generations, I had realistic expectations for portable lawn tools. Even so, this purchase still fell short against minimal standards of quality. In 30 years as a homeowner, this was the worst tool I ever purchased, (but it IS convenient). Be prepared for built in obsolescence and needless replacement costs.
