Even though they were a bit backed up they sent my package through priority mail so it arrived sooner. Customer support is also very responsive. I received a battery from them and am excited to receive their photon gen 2.
The battery has been very good so far no complaints.
Great batteries for a very good price. I have been using 2 of their high power packs for several months now and highly recommend them. They also asked for feedback about their products and then followed through on the things I suggested! Highly recommended
