Whenever I am doing presentations for school and/or work, I used to worry about whether the batteries in my laser printer would work or if the people I was presenting to could see the laser dot. Now I do not have to. With the teaching pointer by Sandao, people can immediately follow along with what I am pointing at. If someone is not paying attention, I can also use it to point at them. The good thing about it is that it fits easily into a pocket or briefcase due to the collapsibility. I do not need to bother with those tiny cell batteries either which is a huge plus. #RankBoosterReview #Sponsored #Sandao
