Bad Shipping

2 months ago
The item is in a shelf hanging plastic that you can barely cut with your scissors, which is fine however, they shipped it in a plastic bag that made that really hard plastic container for the battery explode into little teeny tiny pieces. It needs to be shipped in a box or a padded bag.

Yes, I recommend this product.
