The DELUX M627 is a modular, ambidextrous gaming mouse with two buttons on each side. It comes with magnetically attachable finger rests for both sides, meaning you can change its ambidextrous design to a more ergonomic one for right or left hands. It's well-suited for all grip types and nearly all hand sizes, but extra-large hands may drape over the front of the mouse when using a palm grip. Performance-wise, it has a wide CPI range, a CPI you can adjust in increments of 100, and a low lift-off distance. You can cycle through five CPI profiles with the button below the scroll wheel, and the RGB lighting strip at the front of the mouse changes colors depending on the profile you're on. Unfortunately, its click latency is high, and some gamers may prefer a more responsive-feeling option.
Our Verdict
The DELUX M627 is decent for office use. It feels well-built, and it comes with modular side wings, so you can use it as an ambidextrous mouse or attach the magnetic finger rests on either side to give an ergonomic right- or left-handed shape. Unfortunately, it doesn't support Bluetooth, and you can't pair it with multiple devices at once. Also, its scroll wheel doesn't have L/R tilt buttons or a free-scrolling feature.
- Modular design with magnetic finger rests.
- Onboard memory.
- No Bluetooth support.
- No L/R tilt buttons or free scrolling.
The DELUX M627 is okay for FPS gaming, but it has high click latency, so it may not feel responsive enough for gaming, and it's heavy. Also, its mouse feet don't glide very smoothly, and its braided cable isn't very flexible. On the bright side, it has a comfortable, ambidextrous design, and it comes with magnetic finger rests that convert it into a right- or left-handed mouse. It has a wide CPI range and a low lift-off distance, although it isn't as low as other options.
- Modular design with magnetic finger rests.
- Low lift-off distance.
- Fairly high latency.
- Fairly heavy.
The DELUX M627 is decent for MMO gaming, but it doesn't have nearly as many mice as dedicated MMO mice do. That said, you can reprogram all the buttons it does have using the dedicated software. It feels well-built and comfortable, and it's suitable for all grip types, although people with extra-large hands may struggle with a palm grip. It has a wide CPI range, a CPI you can adjust in increments of 100, and a low lift-off distance; however, its click latency is high, which isn't ideal for fast-paced games.
- Modular design with magnetic finger rests.
- Low lift-off distance.
- Fairly high latency.
- Doesn't have nearly as many buttons as MMO mice.
The DELUX M627 is a mediocre ultra-light gaming mouse since it's significantly heavier than most dedicated ultra-light gaming mice that we've tested. Also, its braided cable isn't very flexible, and its mouse feet have many sharp edges that cause a scratching sound on desks. Also, the click latency is high for a gaming mouse, so some gamers may prefer a more responsive-feeling option.
- Modular design with magnetic finger rests.
- Low lift-off distance.
- Fairly high latency.
- Fairly heavy.
The DELUX M627 is decent for travel. You can use it wirelessly via its USB receiver, and you can store the receiver in the mouse when not in use. It feels well-built, and it should fit in most laptop bags, but it's much bulkier if you attach the finger rests. Unfortunately, it doesn't support Bluetooth, and the right side buttons don't work on macOS.
- Modular design with magnetic finger rests.
- USB receiver storage.
- Onboard memory.
- Fairly heavy.
- No Bluetooth support.

The DELUX M627 is an okay wireless gaming mouse. It's one of the few gaming mice we've tested with modular parts, which let you swap out the sides to turn it into an ambidextrous, right-handed, or left-handed mouse. It's an interesting option if you want to customize the feel and shape. Unfortunately, it has a fairly high latency, which may not feel responsive enough to some gamers, and while its lift-off distance is low, it isn't as good as some other options at its price point.
