DeLUX Seeker Wired Ergonomic Vertical Mouse with Thumb Wheel, Optical Computer Mouse with 6 Programmable Buttons, 4000 DPI, RGB Backlight, Removable Wrist Rest for Carpal Tunnel (M618XSU-Black)

tl;dr: Very premium, very unique, almost perfect ergonomic mouse.Pros+ Ergonomics+ High quality fit and finish+ Satisfying tactility+ Truly silent click+ 3 Wireless modes + wired mode+ Side scroll "ball" is a neat bonus feature and I prefer it to the MMB scroll wheel.Cons- Back/Forward buttons (M3 and M4) are very inconvenient for me to reach- OLED screen fails in practice to increase convenience of checking DPI or connection setting due to placement---Detailed review below:---I just received this mouse and started using it today, so I can't speak for longevity or reliability, but I have purchased a different DeLUX mouse, the M629BU, and thought it was a decent buy. I had no issues with the M629BU for ~6 months before the MMB gave up the ghost; this was definitely unfortunate but not completely unexpected for a very very inexpensive mouse, and I don't know whether this was an issue with that mouse or just an unfortunate happenstance.This mouse costs 3.5x as much as the M629BU so comparing the two isn't really fair to either product.I have used one other ergonomic mouse - though I am not sure of the brand or model - about 4 years ago in my workplace and was not happy with the design, layout, or wireless feature. It frequently disconnected, would often stutter across the screen and ignore inputs. This may have been due to the poor battery life, 2.4ghz connection, or some sort of overzealous power-saving feature.As far as similarly-priced mice, I have used the Razer Basilisk Hyperspeed V2 (for which the wireless dongle stopped working entirely after 13 months and, to my chagrin, for which Razer does not sell replacement dongles), and a Logitech G502, which began to have issues with ghost-double-clicking and for which the scroll wheel stopped working after about a year. These issues I have described with these two mice from well-known manufacturers are commonplace and well documented, despite the rave reviews (trust me, google it).First impressions: The unboxing experience leaves much to be desired. I am really not a snob about that stuff, but it does generally show that the manufacturer has a desire to present the product in a manner that shows some care put into every aspect of the product experience, even presentation. This isn't a big deal to me but just something to note.The packaging was a sleeve with some typical info about the product printed on the outside. Upon removal of the sleeve there is encased a plain rectangular black cardboard box with the mouse inside as well as some accessories. The contents of the box were as follows:1. The mouse2. The magnetic base which attaches to the back of the mouse3. A solid back-plate to replace the "aerated" one attached by the manufacturer4. A very soft, braided USB A to USB C cord.5. A small booklet containing basic information about the mouse, including the functionality of all of the buttons, locations of indicator lights, etc. and a link to the DeLUX website where you can download the driver software.The Fit and finish of the mouse is extremely nice, maybe the best I've ever seen. All of the seams where the parts of the outer shell meet are consistent and have tight tolerances. The click of all of the buttons is tactile and satisfying, as is the magnetic attachment of the base. The texture of the material is... satiny? It's difficult to describe; almost silky, but not glossy, and not quite matte either. My favorite part about this mouse, besides the excellent ergonomics (it is very comfortable, far more so than any non-ergo mouse I've used), is the silent click; It is basically inaudible to me with my desktop computer fans running a few feet away from me.I only have two gripes with this mouse:1. The placement of the back/forward buttons is a little too low and forward for me to reach easily with my thumb. If they were each maybe 3mm higher and 2mm back, that would be perfect for me. (Maybe in V2?)2. The OLED screen is very cool, but the placement of the screen is on the top in front of the DPI switching button and angled sloping downwards, making it basically impossible to see at a glance without lifting the mouse and just looking right at it. Overall, it is significantly less convenient than it would seem conceptually.Other notes: I have large hands (7.5" from wrist to the tip of my middle finger) and use a palm grip. This mouse fits perfectly in my hands. I am not sure if this mouse would be comfortable for someone with small hands or a claw grip.I try to return and edit my reviews after a few months to comment on reliability, but after my first day of use I am impressed and I look forward to seeing how it holds up.

I am extremely happy with this nice compact vertical mouse. It has a scroll ball on the left side and a vertical scoll wheel on the right side. You can scroll vertically or do both depending on what input you want to use. Of course you can use the optical mouse to do the same. I also included an image of the driver interface. Most of the functionality can be adjusted if you download and install the driver software, to include the color gamut that is displayed. This mouse is imported and is made overseas. It took me a while to download and install it, but I was at a resort, and that night it was very slow. It is much faster now, I just need to say it took a long time for me to download it that night.I have some physical issues with my elbow and this vertical mouse is compact and easy to use and can be customized to include changing the DPI setting as desired. It also comes with a easy to attach and remove flat platform so your wrist can sit on it rather than the desk or mouse pad. I highly recommend this mouse but please install the driver to enable full functionality. It was at the website in the manual. I have not noticed any discernable lag. Every function seems to work well. I am happy and it looks good too.

I like to use a vertical mouse from time to time to avoid wrist pain. I did have an issue with wrist pain from using a normal mouse, my first vertical mouse fixed that.My primary issue with vertical mice is they feel to small for me. My hand drags across the desk when using one. I originally liked the shelf that can be attached to the bottom. This keeps my hand from dragging across the desk which I like. The problem now is my hand is just to big. I’m 6 feet 5 inches and probably normal for my size for reference. With the piece on the bottom I either need to push my fingers together so I can use the buttons like I normally would or rest one finger across the top and use my middle fingers. For me it’s works best without the plate. I do like that it angles back in at the bottom for that plate which works perfectly for my pinky so it’s a little more like holding a ball now vs my had open and pinky dragging on the desk.I really like the display. Very useful for knowing how much charge you have and the dpi setting.The dpi can be adjusted adjusted in software up 7200 dpi. You can have 4 different settings you can quickly change between. The leds are also adjustable in software and of course you can set macros. It also comes with a solid panel to replace the one your palm rests on so you won’t see the led light at all if you want.I feel like the price is good, I know how much charge it has and I can easily swap it between the 3 computers I use it with.
