I picked up five of these for use as christmas gifts. Shipping time was between 10 and 15 business days (They sat in my PO Box for an unknown period of time.) They arrived bundled together with 10 AAA batteries all in one layer of bubble wrap in an envolope. They are identicle in appearance and size to the models sold by DX, hence the only difference should be how they measure the power. I've never owned any DX pointer other than a "30mW" so I don't know how they compare. Perhaps someone else can chime in. So here are the power results:
Tests were over ~30sec at 60 degree F ambient temp and are approximate values that include any IR output.
With included alkalines:
peak 9 7 40 9 34
average 7 4 15 5 18
With e[sup]2[/sup] lithiums:
peak 11 8 40 11 26
average 9 5 25 7 14
No, that's not a typo. I double checked and one performed better with alkalines. It's output also looked like a sawtooth wave, climbing slowly and plummeting only to begin another climb :-/. Three were relatively stable and only deviated 1 or2 mW. The 40 peak one deviated up to 5mW
Bottom Line: Not at all bad for $13 shipped. Some outputs may be too high for use as pointers, but I would definately buy again.
