They do not seem to perform as well as I recall when ordering the minis in the past. I doubt I was sent by mistake the 50 puff version. I waited for the "new and improved" to come in stock before ordering. I will email and see what they say. They do have the best price for a disposable real-size but, as is, this is not even close to doable. Yes, I have a zillion kits (minis, tanks etc) but I really prefer the light weight, no fuss, real size disposable. NJOY King should get with the program - $30 for 5. Yeah hello!
