These reviews seem to cover several models of Elecom trackballs - this review is specifically for the DEFT Pro model M-DPT1MR (middle size, between small blue-ball and the "Huge").I have tried several trackballs from several manufacturers, trying to find a decent replacement for my failing Microsoft Trackball Explorer (MTSE). The M-DPT1MR is the closest substitute I have found yet.Although the basic shape does not fit my hand quite as well as the MTSE, the shape still is close enough to provide much of the same comfortable ergonomic fit. The main difference is the lack of a "landing area" at the wrist end of the trackball. With the M-DPT1MR, your wrist will rest on the table instead of up on the trackball itself. HOWEVER, I have found that using the proper wrist pad makes an acceptable substitute, positioning my wrist/palm in a very similar position as on the MSTE (see my comparison photo). The M-DPT1MR looks smaller in the photo, but with the extension of the wrist pad, the hand position is very similar.From the photo, the M-DPT1MR ball looks much smaller than the ball of the MSTE, but the measured diameters are very similar (44mm vs 46mm, respectively). I do not notice any difference due to ball size during usage. Ball operation is very smooth.The center and right button placement is not quite as comfortable as the MSTE - the buttons are a bit too close to the ball, and a bit smaller than the MSTE's. But, I have been able to adapt after using the M-DPT1MR for a while. Not too hard a transition.As other reviews have noted, the scroll wheel has a noticeable "clicking" or notched feel. I personally do not have an issue with this - I only really notice it when scrolling long pages quickly, but even then it is not too bad. Seems to smooth out over time. The wheel's click operation is a bit stiffer than the MSTE, but again surmountable, at least for me. The main left-click button seems perfectly natural for me.The Elecom Mouse Assistant software seems to provide all the control I need, for speeds, inertial momentum, and button assignments. I could map the buttons just as I had done for the MSTE. I like the extra buttons for custom mapping, but frankly have not used them much so far.I do wish it was easier to find an English version of the user's manual - it does not come in the packaging, nor is there a clue about where to find it. Unfortunately, Amazon does not allow me to try to help by posting the links here.All in all, so far I have been quite satisfied with the M-DPT1MR. For many people, it may certainly be a reasonable alternative for the MS Trackball Explorer.

I'm giving this a mouse a go after experiencing a lot of failures on some recent Kensington trackball mice. Overall, I love the shape of the mouse, the buttons feel great, placement of everything is pretty wonderful. The fact that it can operate as a USB mouse, a USB-wireless mouse, or a Bluetooth mouse is pretty nifty, and offers options for using it on-the-go.While it's pretty solid, there are a few nit-picks. Some have mentioned that the scroll wheel feels a bit cheap, and that's true. I've also noticed "sticking" of the trackball, which while minor, is noticeable. I'm hoping both of these issues will mellow out with time as I break it in a bit more (if they do, I'll update this review).Finally, not a negative, but the instructions that come with the mouse and the software are Japanese by default. They give you a QR code for the English documentation and the software quickly switches to English, but I just thought that was an interesting quirk.

If read many of the review you will see comments on poor pointer movement. On the one I received I works pretty well will no movement pointer issues. There is an adjustment period coming from a regular mouse and occasionally as you rest your finger on the track ball as you stretch for the other buttons you will move the ball slightly. The has got better with time and is not an issue with the Deft Pro itself. First impression of the mouse are that it is quite big but as its is designed for your whole hand to sit on it is not bad and as mouse itself does not move it does not create space issues on the desk. The buttons themselves are "clicky" but not overly load. Personally, I like the buttons on the Elecom Bitra better. Its pretty well made and the dual wireless dongle and Bluetooth connections provide connection methods that avoid the antique micro USB cable connection. For me I find on the wireless dongle it goes through batteries pretty quickly. I am not sure if I am using rubbish batteries so may get some decent alkaline ones to see how it goes. For a quick comparison to the Elecom Bitra the trackball on the Deft Pro is easier to control, The Deft Pro fits better in your hand but the buttons on Bitra are far better. Overall, a very nice trackball which really needs to be updated to have a USB-C port on the device.

Great comfort, very easy to use. Took me a week or two to completely adapt.I would love if the scroll wheel was infinite like the Logitech MX mouse

Je n'en suis pas à min premier trackball et c'est le meilleur que j'ai testé jusqu'ici. J'aibde grandes main mais sa taille reste très bonne. Sans fil ou avec tout fonctionne bien et les boutons supplémentaires s'avèrent très utiles.

Con i tasti programmabili il lavoro diventa più scorrevole. C’è posto per un tasto aggiuntivo sotto il mignolo. Avercelo sarebbe l’ideale

Se ha averiado con menos de un año de uso. Ha dejado de encender, la mayorÃa del tiempo conectado por cable. Poco uso, la verdad. Sorprende negativamente que le pase esto a un ratón tan caro. He comprado varios trackball Elecom y estaba bastante satisfecho con la marca.He contactado mediante formulario con el fabricante, a ver cómo resuelven la garantÃa.
