Review title: Great when it works
Product review: When the battery if fully charged, this is the most powerful laser pointer I've ever seen! You can see the actual laser beam as it cuts through a dimly lit room. It's cool for getting kittens to chase the light from blocks away. Seriously though, the biggest and often embarrasing problem with this pointer is the need to frequently change the batteries. It eats through them. If you go a couple days or so, especially if you have it in your pocket or another tight space where it may inadvertently be activated, it begins to work intermittently. It becomes unreliable, but changing the battery does not come to your mind as it still works occasionally. It's green color can also be effective where a presenter and a commentator can have seperate colored lasers. Overall, if you present frequently, and replace the batteries at least weekly, it will add a bold impact to your presentation.
