The Logitech K845 is a decent mechanical keyboard for office use. It's a full-size keyboard that feels well-built, and while our unit uses Cherry MX Blues, you can get it with other types of switches to suit your preference. The Cherry MX Blue switches provide a great typing experience with good tactile feedback, but they can be rather loud, which isn't ideal for quiet office settings. Unfortunately, it has very few extra features and lacks software for customization. Also, its latency is a bit high for a wired keyboard, which might disappoint some gamers.
The Logitech K845 is decent for gaming. The Cherry MX Blue switches on our unit have a fairly light operating force and a short pre-travel distance, which results in a quick and responsive gaming experience. However, its latency is a bit high for a wired keyboard, which might disappoint more serious gamers. Unfortunately, there's no software for customization, so you can't set macros to any of the keys.
The Logitech K845 isn't designed for mobile or tablet use.
The Logitech K845 is decent for office use. The Cherry MX Blue switches on our unit provide a great typing experience, but if you find them too loud for an office setting, you can get the keyboard with another type of switch to suit your preference. It doesn't feel tiring to type on, but some people might need a wrist rest, and one isn't included. It's fully compatible with Windows, and only a few keys don't work on macOS.
The Logitech K845 is decent for programming. The Cherry MX Blue switches on our unit feel fairly light and responsive, thanks to the short pre-travel distance and clicky tactile feedback. It has nice white backlighting that can be customized using the hotkeys. Unfortunately, there's no software for customization, so you can't set any macros or remap keys.
The Logitech K845 is bad for a home theater PC. It's a wired-only keyboard, which isn't ideal if you have kids or pets that might trip over the cable. Also, you need a separate mouse to move the cursor because there's no built-in touchpad. It has media controls, but the legends are printed on and don't light up in the dark, making them hard to see.
The Logitech K845 is a full-size keyboard that takes up a fair amount of space. It's almost identical in size to the Logitech K480 Bluetooth Multidevice Keyboard.
The build quality feels great. It's mostly plastic with an aluminum top plate that feels nice and solid. The body has a slight flex to it, but it isn't noticeable when typing. The ABS keycaps have a rough texture for better grip, and some of the keys wobble when pressed, especially the Enter, Shift, Backspace, and Spacebar keys. There are five rubber feet at the bottom that do a good job of keeping the keyboard in place, and the incline feet shouldn't collapse when sliding the board around.
The ergonomics are okay. Key spacing is pretty standard, and it doesn't feel tiring to type on, but sadly, it doesn't come with a wrist rest. If you'd like a model with a wrist rest, consider the ROCCAT Pyro.
The Logitech K845 has excellent individually lit backlighting. You can control the brightness and cycle between five lighting effects using the function keys. The color is not quite white. There's a blue/green hue to it, although it's more noticeable in a dark room than in a bright one. The secondary functions on the F keys, like media and brightness controls, are printed onto the keys and don't light up, so they may be difficult to see in the dark.
The cable is rubber-coated and retains kinks from the packaging.

The typing quality is great. The Cherry MX Blue switches give nice responsive feedback and don't feel tiring to type on.

The Logitech K845 is a decent full-size mechanical keyboard for the office, but it has very few features, which is expected for a budget mechanical keyboard.

On the plus side, it does have backlighting and feels quite well-built.
The Logitech G413 and the Logitech K845 serve different purposes, as the G413 is designed for gaming and the K845 is designed for office. The G413 is only available with Romer-G Tactile switches, while the K845 has various Logitech GX and Cherry MX switch options. Since the G413 is designed for gaming, it has much lower latency and is compatible with Logitech's G HUB software. It also has macro-programmable keys, which the K845 lacks, but it's limited to the function keys only.
The Logitech K840 Mechanical Keyboard and the Logitech K485 are both decent office keyboards. The K845 feels better built, its Cherry MX Blue switches require a bit more force to actuate, and it has backlighting. However, our K840 unit is fully compatible with macOS, and while it has customization software, there aren't many options.
The Logitech MX Keys is better for office use than the Logitech K845. The MX Keys' scissor switches on our unit are much quieter than the Cherry MX Blues on our K845 unit, so it shouldn't be loud in an open office. Also, it's wireless and has a multi-device pairing feature, has a lower profile, and it's fully compatible with both macOS and Windows. However, the K845 has a higher pre-travel distance, which should help prevent typos.

The Logitech is a full-size wired-only keyboard, while the Keychron is a 65% keyboard that can be used wired or wirelessly via Bluetooth. The Keychron has full RGB backlighting, while the Logitech is white-only. The Keychron has a multi-device pairing that lets you pair up to three devices simultaneously so that you can switch easily between them. If you plan on gaming, the Keychron has lower latency in wired mode.
The Logitech G513 is a much better keyboard than the Logitech K845. Since it's designed for gaming, the G513 has some programmable keys, customization software, RGB backlighting, and a USB passthrough. It also has lighter and more responsive keys, and it comes with a wrist rest. However, the K845 has a longer pre-travel distance, which should help prevent typos, and it's fully compatible with Linux.
The Razer BlackWidow is better than the Logitech K845, although it's mostly geared towards gaming. The Razer has full RGB lighting, lower latency, and outstanding customization software. On the other hand, the Logitech feels better built, and you may feel less tired typing on it because it has a lower profile.
