Question: does anyone know the dimensions of this item? looking for all dimensions but especially thickness (how much it sticks up from the key if laying flat)
Document: Works quite well. The batteries are replaceable if you carefully disassemble the light. Sticks well to cleaned key surface. It's no 800 LUX flame thrower but it's plenty bright enough to light up a key hole, it's intended purpose. I'd recommend this item.
This little key light attachment is absolutely amazing! The LED is bright and sufficient, especially for its size and purpose. The pre-applied adhesive sticks and holds well on the key. I'd totally recommend this product if you're a late night home comer and find it a pest to locate the key holes on your doors. Overall a very simple, and well made product.
Such a great, bright light, and so easily utilized! It's also very handy for locating an item that's been dropped on the couch or under an end table, and is especially great for REALLY lighting up shiny jewelry findings that fall on the floor.
I know from use just how durable and easy-to-use the Thumb-Lite is, and I would highly recommend it to anyone concerned with safety and convenience when entering their home or vehicle.
This is the perfect World's Smallest light. It is very bright. It sticks right on the key making it easy to turn on using your thumb. I will definitely order this again.
I bought this item for my father-in-law who is legally blind. It helps him quickly find his house key (by touch) and the light helps him get the key in the door. He loves it.
I highly recommend this key light! It works great and it makes it so much easier to insert your key when there are no lights available. Awesome! !
K it is small, but its bulky to put on a key, the light is decent at best. better off buying a key with the light on it, much smaller. I should have returned this but oh well.
My husband had hard time to open the door when there was no light at night. Well this problem is solved now, this little light is super bright, sticks to the key perfectly. It becomes like a part of the key. Not too bulky...highly recommended!
I bought one of these just to try since they are so inexpensive. I mounted it on my house key to try and it works great! What is so good is that you don't have to try to handle a flashlight separately or pull out a smartphone for light, just grasp the key and have light. If you have never seen one it may be a little thicker then you would imagine but it must have room for a watch battery and just one on a keyring doesn't make much difference at all.
Answer: yes
