I’m a very happy customer of Camzilla. The batteries on my 4 year old DJI drone died and DJI told me it’s an old discontinued model, you’ll need to upgrade to a new drone. That’s $2,200 down the tubes. Camzilla came to the rescue with some virtually new 2nd hand batteries. They are from the Platinum model so colour Is different but who cares. They work a treat and I fly again! I love these guys.
