I recently purchased a small LED flashlight, marketed under the name GreatLITE, by Great Neck Tools. It failed almost instantly, but the warranty said to return it for either a repair, or replacement, which is what I did. Yesterday UPS delivered a new one that works as it should. I figure anyone interested in their products might enjoy knowing they are quick to make adjustments when something goes wrong. I recommend them highly.
Usual disclaimers. Just a satisfied customer.
