The ADM laser worked like a charm in aligning my telescope. Highly recommended.
Great Laser for the Price
Bought this laser to replace a cheap pen I got a while back. Very happy with the purchase. This laser is bright, even in a moonlit city sky. The locking key on the back is nice for transportation so it doesn't unintentionally turn on and waste the battery. The rechargeable battery lasts a very long time and overall the laser is of good quality. The only drawback is that in the cold (5 degrees C or less) it does start to dim slightly but this is easily remedied by letting it warm up in your pocket for a minute or two. Overall a great purchase! Side Note: This is roughly a 200mw laser, and WILL start to burn dark colored stuff placed right in front of the laser (although it takes a while).
