Very Poor Design In Addition to High Defect Rate
This product would be inferior even if it worked properly due to its features. It uses small circular batteries, which would have made this item impractical to use consistently had it not been defective. However, it vibrated erratically when one or more batteries were inserted, and could not be turned off with the switch at the top. I had to either remove the batteries or put the plastic sleeve back in to prevent it from vibrating.<br /><br />Amazon was great with the refund request, but this product's design is terrible overall.
