Nulea M509 Wired Computer mice

I would purchase again if needed, and recommend. I am new to trackballs. This is my second trackball. The first one I bought was a logitech M575. I got it to go with a laptop because sometimes you find yourself in situations where a mouse is harder to use / no good surface to move it on. It takes just a little bit to get used to moving your thumb instead of a mouse. I enjoyed the experience and wanted a wired trackball for my desktop. This device in comparable in size and layout to the logitech M575. Like a larger mouse, it more comfortably fills a medium to large adult hand. The ball is the same size and weight as the M575. The narrower right click button is actually nice for me, as I can move my middle finger off of it so I don't accidentally click it. Both mouse buttons feel (not measured) about twice as stiff as the logitech, so I don't have to focus on holding my fingers completely off of the mouse buttons to avoid accidental clicking. (This can become a thing as we age and the tendons get just a little tighter, remember to stretch your finger tendons from time to time.) The top of the body of the device has a soft rubber / silicone coating. There are rubber feet to keep it from sliding around on the desk. The cord is plenty long enough for most situations, and has a soft rubber / silicone insulation. It is not quite as flexible as really soft silicone stranded wire, but it is much nicer than the bog standard vinyl / plastic wire and a very nice surprise. The usb c to a adapter seems good quality, but it has just a tiny bit more give than I would like to see. I don't think it will be a problem, but I would recommend a little care not jerking the cable around and when plugging / unplugging. i run linux, and everything is working great. lsusb shows the device as Holtek Semiconductor, Inc.

Price was awesome and it works every bit as good as the higher end trac ball mice.

A good little wired ball mouse. Got this to use with a chromebook I use to run an online dart set up. Got fed up charging up the wireless mouse I was using. This mouse works fine for what I need and wasn't to expensive.

無線方式のタイプを使用していましたが反応に変化が出てきたため今回は、有線式を選択しました。トラックボール式のマウスですので操作に際し、置き位置をあまり変化させた使用方法ではないかなと思い選択しました。 新品時の情況は、軽快なトラックボールの操作感で好印象を持ちました。 好みのもんだいですが、ボタンの操作感も悪くないと思います。コスパは良好かと感じます。あとは、経時変化が少なければよいと思います。
