Bests & Worsts Reviews from Amazon

I purchased this to replace a former Black and Decker cordless vacuum. I read the reviews extensively, and bought this model based on mostly positive reviews. However, my experience was quite different. The vacuum has a pull out crevice tool which is one of the reasons I purchased it. Unfortunately, Black and Decker has not thought out the design of this crevice tool, wherein it would actually remain extended when vacuuming small areas, such as you find in automobiles. Each time the tool retracted, making those tight spots unreachable. If Black and Decker can revise this crevice tool so that it locks in place, then it would be worth the price which is being charged.
