Greetings,
I would also put my $0.02 for Brightguy. Delivery was right on time, and everything has worked perfectly for several weeks so far. The x990 is my night walking light--perhaps a bit heavy but I want to know if anybody is on that baseball field besides me, or down a dark street. This is a Philadelphia suburb, and supposed to be a safe area, but we all watch TV at 11, so I like to have the security of a long throw lamp.
As far as tossing it into the air, I did not buy it to use in that fashion, so if SF has a model that can withstand such abuse and you need that, good luck. I mentioned on an earlier post that this light has brought out quite a few neighbors, who wonder what the old man is doing walking down the street with a superlight. There is a new model from another company that allows carrying only the head, and wearing the battery pack on a belt, but the concept is the same--plenty of light at your convenience.
Would I buy another x990--positively yes. It does what I need and want. If you just want a super torch, there are mod guys on this site who can outdo it, probably at lower cost. It all depends on your skills and needs.
Best Holiday Wishes to All,
Harvey A. Koolpe
