i recently purchased the GeekVape Aegis Solo, which I love. It came with the Cerberus tank and I’ve had nothing but problems with the coils. I ordered a 5 pack and 2 out of the 5 had the bottom part that fits in the base break off before I could put them in. Two burned out immediately and the 5th only lasted 2 days. This is getting expensive. Is GeekVape known for coil problems or should I not order from eightvape anymore? Does anyone have experience with these coils?
