I purchased from them in the past and didn't have any problems, but recently they must have gotten a junk cheap shipment. Their manual batteries are garbage. They only have a 14 day return policy, so after replacing one the 2nd one they said they would not replace again since it is beyond the 14 days, but that is pretty crappy when you receive it defective from the get go. It's basically a disposable because it only works until the battery needs to get recharged. As it doesn't charge. I have multiple chargers and I have my original smoketips that still work. They make it seem like their is no problem with their new supply, but they don't know that I have a few friends local to me saying they have the same issue. They hit weak and they cannot be recharged. I wish they would own up to their problem. I love their prices, but it should at least work. Where else can I go to get a decent price. I wish Smoketip sold manual button batteries. They only have automatics, but the lifetime warranty is sweet.
