cut off blade results

tried 3 different blades, 1. Makita "hi". 2. the hudson fron home depot. 3. the 5 pack fron Harbor freight.
results duribility Miketa 5 times the cuts on the same material appliance tin as either of the other 2. in fact the home depot blade never even got through 1 dryer., and the five pack from HF did almost the work of one Makita blade. the HD blade is the same price as the Makita and it is useless I bought 2 Im taking one back and plan in explasining to the store manager that I dont like getting ripped off. and discovered why Lowes is eating their lunch. the HF blades wernt much better but seemed to have an inconsistency in duty time. the best and in the long run cheepest by a long shot was the Makita.
