Pros: Fits all of my most important stuff for combination work/school days: 4 Flash Voyagers, 45-piece tool kit, USB-IDE-SATA bridge kit, 2 thin text books, 5 subject notebook, 2 pens, 1 sharpie, small CD/DVD booklet case, my 15.6 inch laptop, it's power cable, and the adapter brick with room for a little more.

Cons: Seems obvious, but the more you put in it the more it weighs. Choose your items wisely.

Overall Review: I work in IT and I attend University. I needed something that I could fit all of my work and school stuff into that would also be mobile enough to carry around campus all day and be viable to quickly grab and carry on a surprise service call. This bag meets my needs.

Pros: Small, easy to carry in your pocket or in a backpack.

Cons: Hard to focus. Light isn't bright enough. Can't really see anything through it effectively.

Overall Review: I bought this to use in computer and electronic repair. Didn't help. Fortunately it was cheap and I was able to re-gift it to a friend. I have a stationary tool on my workbench that has arms to hold something and a light+magnifying glass combo for inspecting the object. I wanted something similar that would fit in my pocket for house-calls.

Pros: - Low Price (~$60 at time of review/purchase).<br>- HGST Hard Drives are the most reliable in the business.<br>- Enterprise Grade.<br>- Decent Capacity.

Cons: - Not 4TB Capacity.<br>- Not Free.

Overall Review: I bought two of these for a Synology DS215j NAS which I also bought at Newegg. Both drives arrived in perfect condition, none DOA. They are currently running at a cool 36.5 degrees Celsius.

Pros: - Color screen makes it easy to tell the difference between multiple functions on the Graph screen. - CAS makes it very easy to do many algebraic tasks quickly. I'm a Comp Sci major minoring in Mathematics and I'm already seeing huge improvements in the time it takes me to solve problems. - Built in unit conversion and ability to easily define new units. On my TI-84, this required a separate program and if I wanted the ability to expand my unit selection I had to write my own program. - Can build programs using LUA in addition to the classic TI-BASIC. - Can calculate derivatives, indefinite integrals, and limits. - Dedicated alphanumeric keys makes entering many variables, labels, and text much easier. - Best support software of any TI calculator series. Combines programming IDE, file management, and emulation all into one single high quality application. You can even try all the features for 30-days before you buy! This was a huge factor in my purchasing decision. - Rechargeable battery.

Cons: - The CAS functionality disqualifies this model from use on the ACT (it's still allowed on the SAT though). This was a non-issue for me, but it may be too big a drawback for others. - Not all instructors allow models with CAS. Some do, some don't. I recommend having a TI-84 as backup for those instances. This is the primary con that kept me from buying a TI-89 when I got my first graphing calculator years ago.

Overall Review: I am upgrading to this from a TI-84+ and I am very happy with the switch so far. I especially like being able to type up short sets of notes (ideal for must-have equations) on the PC.

Pros: Small size, light weight, brightness, reliability, adjustable lens, comes with replacement bulb, comes with Duracell batteries. Comes with belt holster but I already had a better one - see "Other Thoughts" below.

Cons: This one is too small to use as a bludgeoning weapon during zombie attacks.

Overall Review: I also own a Gerber multi-tool and it has a holster built for the tool and a mini-MagLite. My previous mini-MagLite after about 10 years was looking worn so I decided to hand that one down and get a new one. Excellent pair of items to carry on your person at all times in case of emergency.

Pros: Excellent quality small optical disc case. Mine *DOES NOT* leave micro-scratches on the discs as another reviewer mentioned. The case is also made out of durable yet light-weight material.

Cons: None.

Overall Review: I bought this to go with the Wenger Legacy 15.6" laptop backpack. It fits easily into a compartment with 2-3 flash drives, which is my dedicated compartment for software storage.
