Query: product works well

I'd agree with the later reviewers that this product isn't the power house hand held that can replace a wired vacuum. However, it will do the job slightly better than cheaper models.I've had two of these over the last year and the quality seems to be consistently good - although on both vacs, the lower power sucking switch is flaky and sometimes doesn't make contact.Battery life on both models seems to be around 20-30 minutes. I try to drain battery life before a recharge and I believe this helps with the battery life. Attachment pieces don't always hold well in the compartments at the bottom of the unit.Given the price reductions on this vac, it is great value and the 4 star rating is deserved.
