"I was happy to receive my order on time. The only thing that I noticed was a little piece of plastic was broke off the bottom edge of the screen. I didn't make a fuss over it because the unit still works. The chamber part that connects to the part that attaches to the heater for use with the bag.As I was attaching the two together a piece of the plastic broke off making the connection unable to hold together. So I tapped it with electrical tape.That worked holding it together. I'm sorry I didn't respond back to you sooner. I've been sick. I use the vaporizer to control my nausea and vomiting. I've been dealing with this for 2 years.NO DIAGNOSIS YET.I still am pleased that my vaporizer that my vaporizer works The item I put in my shopping cart is to remind me when I have 5he money I will buy it."
