Input: This broke on my several times. The first two times it happened they were helpful and replaced the product. I emailed them many, many times throughout May of this year and still haven't heard back from them. My charger case has just about fallen apart. I am very disappointed. There seems to be no other way to contact them but by email, which they haven't been responding to.

Frustrating to deal with when there's only an email address for their customer service.
