The 20,000mW laser pointer is a bit more expensive than the cheapest available, but it's worth it. I have them scattered around the house, which may be true, but in the case of cheap green laser pointer, it keeps stealing your eyes to see things. For the price, I highly recommend it. Great as a gift for someone who can keep it in a bag for a rainy day, and even better for someone who uses it at work every day. The clips are made of metal, hard and even have a hook effect so they don't fall out of the pockets, and the buttons are sealed in the lid so getting wet isn't a problem. However, I'm a little concerned about the rubber switch cover.
It's small enough to grab my mouth when hands are needed. Note the other, not this one, which toggles the function from on to low, and flashes every time the switch is pressed. You won't be annoyed by this. You no longer need direct contact to get the temperature. All you need to do is place an infrared thermometer with a laser pointer at a distance, which will vary depending on which infrared thermometer you have, and the thermometer will display the temperature immediately. I keep this laser pointer in the front pocket of my work shirt every day. There is not a day when I don't use this laser to do something. Also, I leave it on my pants when I run it through the washer and dryer. I let it dry. And it works great.
I wear this high power laser pointer every day and love it. So tell you that a 5mW green laser pointer has the same effect as normal LASIK work, is there one in this case? Yes, they have the same effect, but the results are almost different. Considering the price and using only two batteries, it fits nicely in a pocket and provides plenty of mW. This is good and bad because you can't activate the laser with your thumb. Instead, you need to push it far enough with your index finger to activate. I think this feature is far more important than the extra effort required to activate it.
