Hello, I was a smoker for about 6 years. My brother introduced me to esmokes and vaping about 1-2 years ago starting with the ego-c. I was interested but couldn't afford it at the time. Time went on and I wanted to finally get one. He had switched to Halo because of the outstanding reviews of hardware and liquid so I figured why not. I purchased three starter Triton kits (one for myself, father, and co-worker) along with various e-liquid. First off out of the gate, one of the co-workers' batteries was completely not working properly. I informed Halo and they said they would replace it when I made my next purchase which was great. Not a few days later the other battery he had with the starter kit had the same problem. I delayed contacting Halo about the second battery so that was my fault. My father was strictly using one of his batteries and keeping the other spare battery for if something happened to his main one. Well one day he left his main somewhere and tried to use the second one. It was a complete dud. Did not light up. Did not charge. I contacted Halo and they wanted a picture of the battery contact to make sure it wasn't 'gunked up'. I proceeded to send a picture but I accidentally sent the wrong picture. I sent a picture of a brand new starter kit battery. Needless to say I was more then surprised when they sent me a response saying there was a gunk build up around the contact area in the ridge which is IMPOSSIBLE because it was BRAND NEW. I asked them to show me where they seen this build up and they said it was in the groove around the contact area. I was baffled. They told me it was my fault (or my fathers) and not the manufacturer when it was clearly clean. Considering my fathers battery is as clean and unused as a brand new one... well this thoroughly p***ed me off. I had the least amount of trouble with my starter kit but still had issues. The battery would stick and keep the blue light on and I could hear it sizzling away even though I had let go. It would go until it timed out and shut itself off. I contacted them about it and they ran me through some troubleshooting. They wanted a video but that was near impossible. I couldn't activate my video on my phone to record quick enough and it only happened about 3-4 times a day. I smoke sub-zero as my main liquid. Its a pretty clear pink color but turns to an ugly dark brown and the taste changes slightly but I wasnt very concerned with that because I've seen my brothers, fathers, and co-workers all do the same. I was concerned about the white welts or burns that started to form on the inside of the clear tank. and then one day when I was screwing in the battery it kept going and, to my shock, it wasnt the battery that kept spinning but the actual clear tank had detached itself from the metal base and now leaks. I cant find any faults with their e-liquid. Its amazing. Their customer service leaves something to be desired. The second time I informed them about a battery they made me feel like a criminal for wanting to do an exchange of battery. The third time with them saying there was gunk and a brand new battery just drew the line. We all wont be going back. Not because of the few issues but because of how they treated the issue.
