Query: Very unhappy with this product!

I had reasonable hopes for this and was very disappointed. After waiting 16 hours for the unit to charge, I found that the variable speeds (lo-hi) were useless--nothing really worked well on the low speed. The built in water sprayer broke immediately. The various attachments work with varying degrees of effectiveness--other reviews are correct in that the suction is useless. After 10 minutes of a very bad attempt at a facial, I threw the entire unit away. SAVE YOUR MONEY! THIS PRODUCT IS INEFFECTIVE!
