I purchased the TI-84 for my daughter to use in her 10th grade Geometry class. The course required the TI-84. I asked her how she likes it and she says, "it works well, it's fast, not heavy and doesn't slip on her desk." This is the 3rd TI calculator I've purchased and overall I've been satisfied with their products. We use rechargeable batteries so I'm not concerned that it takes AAA batteries versus a rechargeable battery that comes with the TI-84 Plus CE.
