The chargers work really great! Other chargers I’ve had in the past (which promised lightning charging speed) need at least a few+ hours to budge the battery. Statik chargers start charging right away and your device can be fully charged from nearly dead in less than an hour. I’m very satisfied. ** One of the chargers stopped working within the first month— and their customer service team worked with me to resolve the issue— which ended up w me being sent a new charger ᵕ̈ and the new charger works great! Shipping time is a little slow(compared to Amazon, anyway)— but worth the wait. ♡
