- laser pointer
I got this as a replacement for the laser I purchased several years ago. My first one died because I neglected to remove the batteries between uses. This is a must! So, make use of the provided compartments in the case to store your batteries between uses!
Very weak laser beam. Works great on cats, terrible for astronomy.
Make no mistake, this is still a cheap chinese laser pointer, but it does seem brighter than other's I've had in the past. So for the money, I am very happy
Was hesitant that a $20 laser pointer would work like the $120 one I used to have, but times have changed. This laser works awesome, it's amazingly bright, and everyone loves to see it in use during a star party.
I've had second thoughts since my earlier review of this laser pointer. I bought two of them, but now, both of them, have become very unreliable and disappointing. On rare occasions they work well, which dupes me into thinking the problem is minor and they will work ok, but then when I go to use them the next night they fail totally or have a very weak intermittent beam. There seems to be no rhyme or reason for their failure. I've tried new batteries, tested and sanded the electrical connections and used tinfoil wadding pushed down the battery tube, but all to no avail.
This 532 nm laser pointer appears to be identical to a laser I bought a few years ago of a different brand. Construction and performance is good, though it takes a minute or so to warm up and show a bright green beam. Also, it doesn't always turn on instantly when you press the on button and when it does the beam fluctuates in brightness a little, as though the power connection is fragile. Price wise they're a bit on the expensive side for what is really a fairy simple instrument.
