  • Great production!
Color: Gray Ball
I needed a mouse to keep stationary for my Linux mini computer. I was pleased that this had bluetooth and 2.4ghz. When I got the box I was surprised to find very good instructions and a start up guide. The mouse itself feels excellent for the $20 price point. The ball is locked in from falling out, presumably by some sort of magic or voodoo. The buttons feel like that soft press subtle kind, which is not how I prefer on what you typically see on gaming mouses, but the squishy feel is a trade off to have the clicks be 'silent'. I do have a comment that the ball movement is smooth at low speed. Flicking the ball does expose some of the gritty non-smooth characteristics. Moving it fast does as well. This is best suited for slow desktop icons and menus, and direct mouse movement. I would like to see an adjustable DPI or sensitivity adjustment on the mouse itself because Linux still moves too fast even at the lowest mouse settings. To the company: PLEASE make a square traditional trackball mouse because the inexpensive one on the market is terrible, and the competitors are astronomically expensive. I will buy from this company again in a heartbeat. ... show more

  • Game changer, life saver
Color: Gray Ball
Fantastic idea and great execution. I have a laptop and Steam Deck connected to the same wall-mounted TV and was getting tired of always needing to cross the room every time I needed to move my kbm dongle from one device to the other when I needed to switch. Theoretically both of my devices have native BT antennae, so I figured I'd just connect directly using channels 1 and 2. But I guess there's a lot of competing waves emanating from all the wireless devices mounted on the wall behind my TV, and I was having trouble keeping a reliable connection to the laptop's antenna, so it was really handy that this mouse also came with a USB BT dongle that you can use on channel 3. I never would have anticipated needing a dongle, with native BT being so common in almost any new device these days, but was so glad this trackball had me covered anyway, just in case! It's comfortable to use even when balancing it on the arm of my rocker recliner. I only use it for a couple of hours a week, but after fully charging it on arrival about 6 weeks ago, it's still going strong with no signs of needing a recharge yet. I've been using it in tandem with a solar-powered keyboard from Targus that supports up to 3 devices, too. Together they're so much more convenient than trying to use a traditional mouse awkwardly on a tiny side table and standing up to move a dongle back and forth all the time! Couldn't be more pleased with how they've worked out. ... show more

  • Good for the price, with a things I didn't like overall
Color: Gray Ball
I needed this to be able to connect to multiple devices (PS/laptop and tablet). It was to replace my existing Logitech M570 wireless trackball mouse. I always loved my M570, but I found I now need multi-use capability. I bought this at the same time as a similarly featured Nulea mouse to compare which one I was going to go with. This worked well and connected easily with USB Dongle as well as BT, it wasn't as smooth as the LT or Nulea, but was still nice. Unfortunately, this didn't pair/connect via BT to one of my 3 devices (laptop). USB dongle worked fine though, but dissapointed the laptop wouldn't see it via BT, where it had no issues finding and connecting to the other BT mouse and 2 different BT keyboards. Also, the ergonomics weren't as nice as the M570/Nulea. The buttons were not at the same nautral position as the other 2. And, the scroll wheel was at a strange angle & canted off to the side strangely. I was able to get used to the new position, but it wasn't optimal for me after 20 years with the logitech (although I didn't see it as a deal breaker by any means - specially for the price!). but that, along with the quirk of not being able to connect via BT to the laptop caused the Nulea to win my deciding vote (which was also a bit smoother and a lot closer in ergonomics to the LT M570, while being a bit bigger in size). Overall, this was still a nice trackball mouse at a great price. My son loves it for gaming and said he actually likes it better than my old M570 I was going to hand down to him, so we are keeping the ProtoArc and he will be putting it to use! Can't comment on the battery life as I have only had it a day. ... show more

  • Incredibly good quality and value for the price
Color: Gray Ball
I purchased this mouse when it was less than $22. With that said, I am blown away by the quality of it for that price point. Name brand manufacturers can't hold a candle to that in my opinion. I am very happy with the overall build quality, it is constructed from a thin and lightweight plastic. Matter of fact, the overall heft of the device is rather poor. But that doesn't bother me because I purchased this mouse to travel. It fits nicely in my bag, but is a little more bulky than traditional mice - which is to be expected. It sits well in my hand and was very easy to setup with my laptop. It seems to have up to 3 different selectable Bluetooth connections. They can be switched between using a button and LED on the bottom of the mouse. Great for use with multiple devices. It even includes a dedicated USB dongle for devices that do not support bluetooth connectivity. As for features, again I am blown away by what this mouse packs inside for only $22. Good scroll wheel, dedicated forward and back buttons for web browsing, and a dedicated DPI button to change sensitivity on the fly. You can charge the mouse while using it (i'm looking at you, Apple) and the battery life is excellent. I rarely need to charge it and I use this mouse daily. I highly recommend this mouse to both the seasoned professional, and also the newbie looking to get started using a trackball. ... show more
