At a Glance
The Good: Quiet clicking, side scroll wheel
The Bad: A missed opportunity with no side-to-side scrolling
As with the Silent Mouse, the SM-5000 is deathly quiet. You don't even realize just how quiet it is until you do a side-by-side testing with another mouse. While this feature may seem silly to some, the company says it can be crucial for those who work in such environments as TV or recording studios. (As someone who work at home, this is less important to me. I don't even have coworkers to annoy.)
Nexus has a video on its website demonstrating the mouse's clicking technology that you can find here. This is the kind of feature that appeals to a very niche market, and those who are in that market know exactly who they are.
This 2.4GHz optical mouse comes with a nano receiver and the all-important nano receiver placeholder, located on the underside of the mouse. In my book, this makes it a reasonable travel solution, although it is certainly much larger and heavier than your average travel mouse.
The SM-5000 is also much wider than the SM-7000, and it curves with the hand in an ergonomic shape. Ergonomic designs vary among manufacturers, and what's comfortable to one is not the case for another. However, I used this mouse regularly for about two weeks and found it to be very comfortable with no signs of aching wrists or fingers. The downside to this curving is that left-handed users are pretty much out of luck with this version.
Other cool features of the mouse include a DPI selection button, discretely located above the side grips, that lets you switch between 1000, 1200 and 1600 DPI, which is an extra DPI choice over the step-down model.
There is also a choice of three colors: black, blue and gray. It is important to note that the colors are extremely similar, and it was difficult to differentiate even when holding all three next to each other. The SM-5000 has the same velvety side grips as its smaller sister.
The mouse runs on two AA batteries, and it will go to sleep after a period of non-use. At first I thought the batteries were dying extremely quickly (there no indication of this feature on the packaging or the company's website), but I realized that clicking the mouse turns it back on. It is not enough to drag the mouse, as is the case with other mice that have a sleep feature. There is also an on/off switch to further preserve battery life.
The Back scroll wheel, placed just above the thumb, is a great detail. It’s a very cool replacement to the Back button that many mice have. The only thing I really wish is that Nexus has extended this feature to include side-to-side (a.k.a. horizontal) scrolling, similar to what’s found with the Eclipse Mobile Mouse. It seems like a missed opportunity.
The Bottom Line
With an $39.99 MSRP, the SM-5000 is slightly more comfortable, slightly more detailed everyday mouse. It’s also $15 above the entry-level Silent Mouse, so that Back button should probably be an extremely important detail for you to make the jump.
