Introduction: This is not actually a
review of the Cougar 700M gaming mouse, but rather an investigation into the
issue of mouse buttons "double-clicking" when only a single click is made.
Below are my observations and my investigation into why my 5 week old Cougar
700M gaming mouse started going crazy this winter. A substantial part of the
article is based on my review of the mouse posted at Amazon, where I
purchased the 700M.
The Cougar 700M has some good features, but I am writing this review because
of the problems that I encountered with the first mouse product that I have
purchased from this company. I am not a big fan of the "Transformer'
appearance of the mouse, and that is not why I bought it in the first place.
I wanted a mouse with high precision that had good placement on the buttons.
In general I like the button layout on the 770M, and the feel of the mouse
in your hand is good. I don't like the deep grooved surfaces on the left and
right sides, they do not need to be that textured, and they tend to pick up
dust and other debris over time. They are also hard to clean because the
grooves are relatively deep and very narrow. The braided cord also tends to
pick up dust and lint over time. The software is good, and gives you lots of
control over the mouse setup. You get 4 settings for different
Now for the problems. After about 5 weeks of
normal use (no dropping or other issues that might have affected
reliability) the left mouse button started performing "double clicks" when
only a single click had been made. At first I did not pay too much
attention, but it began to happen more frequently, often while working on a
spreadsheet or when selecting files from a folder. So rather than selecting
a file or folder, the file or folder would open. I would go to select a cell
in the spreadsheet, and instead it would go into text editing mode while I
was trying to do a "Ctrl-C" to copy the contents of the cell. As this
happened more and more, the mouse became less and less usable, and very
I began testing the left mouse button
extensively to see how often the double click problem happened. I would go
across a row of folders on the desktop and single click on each one to see
if the folder was selected, or opened. Sometimes I could go for dozens and
dozens of clicks before a folder opened, sometimes it would happen in the
first 10 clicks. The company claims that the "Omron microswitches" are rated
for 5 million clicks, so it is curious that my 700M started having switch
problems after barely more than a month. When it became obvious that the
problem was not going away, I contacted the company (The HEC Group) to
request an RMA to have the mouse replaced under warranty. The first reply
was swift and decisive:
As Amazon is not one of our authorized
resellers, please process returns with Amazon.
HEC GROUP USA
I wrote back to explain that the 30 day
return period was over and that I needed to process the RMA through them.
Again, I got a swift reply:
"When purchasing on Amazon, if that
particular ad for the item states " Sold by MALABS, fulfilled by Amazon"
then warranty service can be processed by HEC as MALABS is one of our
Unfortunately, that is how the rules work as
there are many individuals and small stores out there that sell through
Amazon, and we cannot authenticate the nature of the products unless they
are our registered resellers.
HEC GROUP USA
The mouse was sold from and fulfilled by
Amazon. I found it extremely strange that a small outfit like MALABS was
considered to be an authorized reseller, but that Amazon was not.
Nonetheless, I contacted Amazon and explained the situation to them, and
despite the fact that they did not have an obligation to fulfill Cougar's
warranty, they immediately cross-shipped a replacement and sent me a return
label to return the defective mouse. I have the new mouse installed, and so
far no double click problems. We will see what happens over the next few
weeks and months. If I have any problems I will update this review.
*Update 1: My second 700M Cougar Mouse
I received a new 700M and at first all was
well. However, within 2 days the new 700M mouse began to show the double
click problem much worse than the first one. Sometimes almost every click
was a double click (folder or file would open rather than just get
So I began to think that it must be some
other problem with my computer (Intel i7 3.3GHz, 12GB RAM, Windows 7
Ultimate). I went into full diagnostics mode.
1) I first moved the USB plug for the mouse
from a USB 3.0 socket to a USB 2.0 socket. Same problem.
2) I put an older (~ 1 year old G400s)
Logitech mouse on the original USB 3.0 socket. No problem with double clicks
at all using the Logitech mouse.
3) I disabled the Cougar mouse control
software (UIX) at Windows startup. Same double click problem.
4) I adjusted the double-click speed in the
Windows 7 mouse control panel. No luck.
5) Plugged the 700M into a different Windows
7 computer (I noticed a very long driver install time) and guess what? The
first click opened a folder rather than selecting it! The problem was just
as bad on a different computer, without the Cougar mouse control software
having ever been installed.
6) Just for the heck of it, I plugged the
700M into a 14 year old Windows XP computer that was still functioning well.
The first click on a folder opened it!
The bottom line was that there appeared to
be something very wrong
with some Cougar 700M mice. Maybe a bad batch of switches, maybe a design
flaw in how the switches are mounted in the aluminum frame. Who knows? I have
had many mouse buttons fail to work, but I have never
experienced this accidental double-click problem with mice in the past, and I have owned many
different mice from different manufacturers. Right now the Logitech G400s is
working perfectly. It is not as nice as the 700M, but it doesn't make
accidental double-clicks. I have uninstalled the UIX software, am returning the
mouse for a refund, and I won't be buying mice from Cougar until the
problems are corrected. Cougar
mice are made by a Chinese company known as the HEC Group who specializes in
aluminum, pharmaceuticals and resorts. Clearly, they are not focusing on
their computer hardware quality.
*Second update: After looking into the
issue more I see that Logitech mice have gotten many complaints about this
issue (although I have not seen this particular problem with any Logitech
mice I have owned, which number in the dozens). However, one person on the
Logitech forum mentioned that in low humidity environments an electrostatic
charge can build up on the plastic, and cause the microswitch to misread the
clicks. We just had a polar vortex come through with temps around 0, and the
humidity in the house is down to around 38%. Using your breath to humidify
the switches supposedly fixes the problem. I have the 700M boxed up and
ready to ship back, so I did not test this to see if it worked. Either way,
it is a design problem that could be easily fixed with metal switch covers
that are grounded. I am tempted to take it out of the box to test it. If I
do, I will update.
*Final update -SOLVED; I couldn't resist. I
had to test out the low humidity hypothesis. I took the 700M out of the box
again, and plugged it in. The problem was severe. I breathed some humidity
onto the mouse, and immediately the problem was lessened, but not gone. I
slipped a small piece of aluminum foil under the left switch and touched it
to a metal object. I removed the aluminum foil and breathed on the mouse
again. Problem gone. Unfortunately, we are having a very cold period now and
our whole-house humidifier struggles to keep the house at 38 to 40% relative
humidity. So until this mouse is redesigned with grounded metal switch
covers, or with special non-static plastic switch covers, I just don't want
to keep breathing on my mouse to prevent the double click problem.
There is no way to be sure without more testing,
but my guess is that the 700M suffers from its overall design. The aluminum
frame is one of the best features of the 700M, making it feel better than a
plastic mouse body. But the plastic switch covers apparently build up static
charge under use and low humidity conditions, and this can discharge to the
aluminum body in a way that registers more than one click.
