Good for small rooms and reduces odors
on March 24, 2021

Verified Purchase:Yes
Works well for a small room as it states. Replacing the pre-filter and filters is simple.
I got it primarily to help reduce tobacco smoke from a roommate. It does help reduce it enough to make a difference.
It does not do much on the low setting and medium is considerably louder. For noise sensitive people, it still emits an audible hum even when off.
I found it best to just run on low when in the room and medium/high when out. Position it next to where a source of contaminants or an odor may be coming in for best results.
When using a new filter there is a bit of a smell coming off of it. It does reduce greatly after some use.

Good mouse, best for a claw grip
on March 24, 2021
Posted by: dstein
Verified Purchase:Yes
Overall the mouse seems to be of great quality. However, it seems to be more built for a very forward claw grip.
The thumb buttons are very far up and awkward to feel/touch for my relaxed palm grip. I'm used to a G502 and those thumb buttons are bigger and more centered.
Another issue with the thumb buttons for me was they are recessed along the mouse. They have a pointed angle outwards and they also increases the difficulty of feeling/pressing them.
I have an average sized hand and I just couldn't comfortably keep my hand far up to reliable hit all 3 thumb buttons.
If you have a claw grip this may not be much of an issue.

Good value for the size
on March 24, 2021

Verified Purchase:Yes
Great value for physical size and storage size. I use it primarily for backing up my systems.
My only concern is that the flimsy USB port is a single point of failure on the drive. If the connector fails for whatever reason, you cannot simply pull the drive out of the case and use another enclosure.
The USB connector is part of the drive's board. There is no SATA connector that you can use with a drive dock or new enclosure. Unless WD changed this be advised servicing this past warranty may be extremely difficult.

Good keyboard, but too sensitive for me.
on March 24, 2021
Posted by: dstein
Verified Purchase:Yes
I wanted to like it, but the keys are way too sensitive for me. This was on the OPX switch verson. I was getting a lot of accidental key presses in games and while typing. My old keyboard was a G710+ with MX Brown switches. The 1.0mm and no tactile feedback on the optical switches don't work for me. I know the longer I would use it I would train my muscle memory, but the return window isn't long enough to be sure.
The RGB lighting and wheel are very nice, as well as the soft/magnetic wrist rest. But I'm not a fan of the glossy center piece for the logo and key indicator lights. The media keys are also a little wobbly and can be pressed the on side without registering a key input.
Software wise I experienced the iCUE software crash frequently when double clicking it in the taskbar, making me relaunch it. I didn't get a lot of time to spend with lighting options and macros so I can't really give a lot of input on that. I will say the ability to customize nearly any key on the keyboard is a huge improvement over Logitech's software.
I would love it if the K100 came with a MX Brown or Red equivalent version and the media keys were more solid. Also, the placement of the wheel is awkward. If it was on the far left side or right side it would be more convenient to use frequently.

Good Design

The LCD screen provides useful information at a glance. One side of the plugs is for Surge+Battery and one just Surge protection. And the top plug is spaced out to help when plugging in larger power bricks/adapters.
