Delivery and packaging great. It came boxed and had incomplete instructions. I get IV infusions as well as pain-block injections. To prevent the doctor from injuring me I chose to purchase the product. When I brought it in to both individual (unrelated) doctors to have them use the machine both found the power of the LED light insufficient to get the job done. Both doctors even tried lowering the lights in the procedure room. The doctor who performs the nerve blocks had more issues simply because there were more sites to target and needle. The area near the mandible and neck worked well but the upper/lower back had issues. As for the IV procedure I have difficult veins to track and the light didn't help much in the arm/hand. As for the incomplete instructions ....the words simply vanish mid-sentence in the warnings area. I don't believe these are the Sellers issues, they are simply selling the product. The manufacturer is the problem. I would recommend the Seller but not the product.
very good
