I got this to point at my co-worker's things. It does a great job of pointing at those things. I recommend this product if you would like to point at things without using your finger. Maybe they're far away things - further than your finger can reach. This will help with that. The wrist strap and retractable capability are nice bonuses.
Also: the black tip can be replaced with (an included) white tip, in case the things you would like to point at are black and you need more contrast.
Update: I have lost my pointer. I am distraught. I need to order another so that I can continue to point at my co-workers' things. I suspect foul play.
