Tendlite Red LED Light Therapy : I ordered on a Saturday and received the very next day, even on Sunday around noon, as promised. very surprised and excited to hopefully receive some relief from my lower back pain. My initial impression of the case and content of the Tendlite was very positive. You could tell immediately this is a very high quality made product, from all the items included in the case and the feel of the Tendlite unit in your hand. Just the feel of the metal machined unit itself is engineered quality from the on off switch to the inverted Red LED light and dual batteries, although you only need one. They include the new very powerful BRC 18650 3000mAh 3.7 V Li-ion batteries, charger, lanyard, sunglasses, case just for the unit itself to carry in your purse or briefcase and a very nice larger zippered protective case to carry or store all items.
