Query: Not the Answer to Underpowered Hand Vacuums

After many small Black and Deckers that had to be replaced because the battery packs would not take a charge and could not be replaced, I thought it was time to try the competition. Unfortunately, I was unable to evaluate how this model worked as the cheap plastic catch that fastens the air horn to the body was broken out of the box. This was probably my good luck as it undoubtedly would have broken later and rendered the vac useless. I returned the unit and replaced it with a B&D CHV1400 which is a bit larger than I like, but an otherwise impressive unit.
