I have to update my review because the last approximately 8-10 coils I have bought here have all broken within a day or two of first use. I have been using the same two shatter pens for awhile because I like them, and come here because they sell the replacement coils I need. Previous to these last bunch of 8-10 coils failing miserably, I had no problems with them. I would get about a good month of use out of each coil. Then one day when I went to get one, it looked a little different and came in different unlabelled plastic packaging, instead of the little box it came in before. I thought it was the wrong one but I was assured it was just the "new design". I got home and it did fit and fire, but after using it ONCE, it said "no atomizer" and ceased to work again. I went and got another, and same thing. I then switched back to my old back up pen instead. I have bought approx 8-10 of them in the last 6 months trying to get it to work. (I would buy the coils elsewhere but no one sells them). I bought another one a few days ago and it happened AGAIN. If you load any more than a quarter of an apple seeds amount into the pen, the ceramic coil will crack and there is no fixing it. From previously working in the industry and seeing what kind of sources companies buy from, has lead me to believe that this store is selling counterfeit coils. Ones that are not made by the same company that produces the product, and are inferior and cheaper. I LOVED this store, I told anyone who would listen how great it was. But this has really rubbed me the wrong way! Not only are you selling a worse product, but you are selling it at a MUCH HIGHER price than you charged for the original REAL coils about a year ago. So either the company has cut costs, raised prices and started making shittier products, or you guys have found a cheap remake of the coil that you can buy in bulk online from China. The latter is seeming much more plausible. Buyer beware! read more
