The most comfortable trackball I have ever used

RHAugust 19, 2025

I've been a trackball user for about 12 years at this point, but the only trackballs I've used have been thumb trackballs. I have had Logitech M570s, M575s, and a couple of MX Ergos. I decided to give a finger trackball a try and the Nulea M505 was reasonably priced for something I may or may not have liked. After I received the Nulea M505B, I had a few day adjustment period to not left click randomly, but by the end of the first day, I can say I immediately loved the design. It's incredibly comfortable, fits your hand well, and the large trackball is something I can say I enjoy a lot more than the typical thumb sized ones. It simply feels more intuitive and more natural to use a trackball this way. I ended up buying an additional one to have on hand for when this one dies and just in case I couldn't find a replacement of the same design. Functionally, you would think that the function of having your right click be on your ring finger be weird, but you adjust pretty fast. All the clicks are easy to register and I haven't had any issues there. Scrolling works well, and the middle click is just the right stiffness so it's easy to press but not accidentally when scrolling fast. The only negative thing I can say about this mouse is the device switching is on the bottom, and I switch between 3 different devices regularly while working from home so it gets somewhat annoying having to lift to switch connections. However, switching to a different device, whether it's the wireless, or one of the Bluetooth connections, it's fast. I have had zero issues when reconnecting to the previous devices and it's always been connected before I even set the mouse back down. Read more

Quality mouse with a smooth, solid, satisfying feel

Railings proSeptember 13, 2023

I've been using an elcom thumb trackball mouse for a couple of years. I was "underwhelmed" when I got that one, as it has a very cheap, jankety feel to it. This one, the Nulea, is what I was hoping for when I ordered the elecom. The Nulea has a very solid feel, the trackball is insanely smooth and satisfying to use. The buttons have a very solid click (my elcom will audibly click sometimes, without registering on the computer. Very annoying.) It has a nice matte finish to it. I imagine that'll probably wear through fairly quickly, but it sure looks and feels nice while it's new. Even though it took me a couple of times to get used to, I prefer the index finger location for the trackball, as it feels easier for me for fine motor skills. It pairs nicely with my PC and my iPad via Bluetooth. I haven't tried the dongle, I'd rather not have that hanging up on my computer bag when I put my computer away. So far, it seems that I won't have to. Yay! The only thing that I am not impressed with is the scroll wheel with the iPad. It seems to vary in speed as you scroll through content (perhaps in relation to what you scroll through? I haven't figured that out yet). I'll be spinning it as fast as I can and the page I'm on will be barely crawling by, then it will suddenly lurch forward at a speed you would expect, then return to it's turtle pace, seemingly randomly. I've only used it for a short time on my PC, but the scroll wheel seems to behave perfectly on it. It came charged, I have not had to charge it yet. Nice not to have to put batteries in it. Packaging was really nice, I typically don't care about that much, but unboxing this thing made me think that it was going to be high quality. I have not been disappointed. I love the size of the trackball, but I kinda wish the whole mouse were smaller. It is reasonably comfortable, but I'd like to take it with me sometimes, and it is huge. There is palm support engineered into the back of this thing. It seems to me that they could have eliminated that by chopping 2" or so off of the back and allowed your palm to rest on the desk, then made the whole mouse 1/2-3/4" shorter, vertically. But, maybe they tried that and this felt significantly better? If your not packing it in your computer bag, it's fine as it is. Bottom line, even with my minor gripes, this is my favorite mouse to date. This thing is solid and is very satisfying to use! Read more

I like the center mouse ball. It moves so smooth and easy to control. It is made with buttons on both sides to help complete your projects. It was worth the money. Read more

It's a decent mouse...but not perfect.

StarglowDecember 4, 2024

It's really hard to find a good trackball mouse these days but I picked this one based on it's features and price point. It can support up to three devices but the active device selector buttons are on the bottom of the mouse instead of the topside which is really annoying if you need to easily switch between paired devices on the fly. I like it that the mouse is rechargeable, but I have to recharge it more often than my other rechargeable mice so perhaps the light ring surrounding the trackball drains the battery faster than mice without lights. The trackball falls out easily but it pops right back in. Performance wise the mouse is responsive but the button clicks are easily heard in a quiet space which may be disturbing for some people. Overall I've been happy with this mouse even with it's minor design annoyances. Read more
