Blows Me Away!
It was time to clean out my business computers. Besides the general dust accumulation, dust builds up on the cooling fins of the CPU which can cause all kinds of computing issues. In the past I've used canned compressed air, which works well, but is getting expensive and doesn't last long. I spotted this on Amazon and, after watching the videos, decided to give it a try. I'm very glad I did! The Wolfbox works just as well, if not better, than the canned air! In fact, it blew out some dust bunnies the canned air had missed!
Canned air runs out quickly and loses power as the pressure decreases, leaving you with an empty can that needs to be recycled. The Wolfbox is rechargeable. After fully charging it I used it intermittently for about 15 minutes and it was still showing a full charge. This amount of use would translate into 2-3 cans of air.
So many things today are slapped together with little thought given to their design. The Wolfbox, however, seems to be well thought out and designed. The Wolfbox includes several different nozzles to direct and concentrate the air stream. To turn it on, just press and hold the small orange button on the back of the handle. There is a 4 led charge indicator on the side of the handle that lights up. Then, simply aim the Wolfbox and pull the trigger. It's just that simple! If you finish the job and forget to turn it off, it will turn itself off after a couple of minutes to save the battery charge. This charge indicator also works during the charging process, flashing while charging and solid when fully charged.
This was discounted to about $40, and that price helped me make the decision to try it. There apparently is a "New and Improved!" version now available at a higher price which promises more power. But this Wolfbox easily met my needs and exceeded my expectations. If you used cans of compressed air this will pay for itself in a reasonable amount of time and will not leave you with a bunch of empty cans to recycle.

A great engineering calculator
Color: Black
I am an electrical engineering professor. it is a struggle to find an inexpensive calculator to recommend to students that can handle complex matrices! There are other engineering calculators that I like much more than the 9750 (such as the hp-prime (my favorite) or the Casio fx-cg50) but this is the least expensive of the calculators I consider "engineering capable". I didn't mention the TI 84 because it handles complex math very poorly, and requires "Euler entry" of polar numbers. The TI-Nspire can do it all, but has way too many menu levels to get anything done.
The 9750 doesn't support CAS mode, and the graphing capabilities are tedious, slow, and poor resolution, but as an engineering calculator I rate it highly because of the complex math and matrix capabilities. I like the larger "graphing" screen for showing larger matrices (not for graphing).

Great value for money, calculus and linear algebra Calculator
Color: White
Great calculator for Linear Algebra. I’ve been using it for 5 months nearly everyday for hours on end and its battery is still holding up. It comes with a sleeve and made from light plastic that is durable. For a cheap calculator, it pulls its weight in matrices, polynomials, and even graphing. My only gripe with this calculator is the limited vector calculations that make it less than ideal for any sort of physics academics.

Recommended!
Color: Pink
This calculator model was recommended by the school for math classes, and my daughter has been using it for quite some time now. She's very happy with it and finds it reliable and easy to use. She especially loves that it comes in this color - it's a nice "girly" option that stands out from the usual standard designs.
