EM05 NL Vertical Wireless Mouse Bluetooth Ergonomic Rollerball Rechargeable Mouse for Laptop, 3 Connection Devices, Compatible with iPad, Mac, Windows, PC-Grey

Avant l'achat, je n'étais pas convaincu mais je me suis dit pour le prix, je vais l'essayer. Lors de la réception de la souris, l'emballage est digne d'une grande marque voir plus. Mais quand j'ai vu la souris et j'ai essayé, testé.... Wow ! Sérieusement, la qualité de fabrication, la solidité, le confort (++++), c'est beaucoup mieux qu'une souris d'une grande marque que j'ai eu à meilleur prix. J'ai une grande main et je n'ai pas besoin de replier ma main pour atteindre un bouton, ils sont à la portée de mes doigts. Bref, bien content, pour moi, c'est 5 étoiles. Un seul hic mais rien de majeur, la roulette de défilement, je l'aurais placé plus haut (sur le top) plutôt qu'entre les deux boutons droits et gauche. Mais plutôt de défiler avec l'index, je le fais avec le majeur, question d'habitude à prendre je pense.

Para uso diario y prolongado es la mejor opción, no cansa la mano y te permite mantener una postura relajada. Y con su configuración puedes variar la velocidad de respuesta, lo que lo hace más cómodo al adaptarlo a distintas actividades.

Un muy buen producto, se siente de buena calidad y es súper útil Al principio es un poco raro para adaptarse a él, pero después de unos minutos de uso es súper intuitivo Lo recomiendo 10/10

Wasn’t sure I would like the vertical trackball but I’ve grown so used to it that it’s now my preference. The battery life is great and the buttons are holding up well. Much easier than a mouse for RTS games in my opinion. The cursor can jump quickly by default but you can adjust it in the settings. I like this one and will probably get it again when it breaks down. Seems pretty sturdy though so I’m expecting at least a 6-7 year lifespan here. I’m 6’2” with average hands for my size. The feel is nice and the wheel works great. It’s a little bulky so many not your “travel” trackball but a perfect one for the default desk work.

To preface, this is not my first Protoarc product. I've also used their EM03 trackball, but that one is a finger ball (the trackball is located up front instead of on the side) and not angled, which doesn't help with my wrist pronation and carpal tunnel issues. Enter the EM05. Very solidly built mouse but doesn't have a lot of weight to it, so some people might not like that it doesn't have that "grounded" sort of feeling. Otherwise it punches above its weight I find - easy to connect to any device via usb-c, 2.4ghz usb dongle or bluetooth wirelessly. The trackball rolls smoothly and is very easy to pop out and clean, but the ball won't just drop out of its slot. The metal scroll wheel feels okay but still lacking compared to the industry standard in the Logitech infinite scroll wheel in terms of smoothness and tactility. I also like that it has this sort of extended "lip" at the bottom to cradle the edge of your hand as you cradle it around the mouse. The angle on the EM05 is very comfortable compared to other vertical trackballs I've tried prior like the MX Ergo. I personally prefer the steeper angle so I can get my wrist as vertical as possible to avoid the overpronation but obviously not everyone will like this. For any left-handers wondering, this mouse is unfortunately not going to be for you with the buttons all located specifically for right-handers. Hopefully Protoarc produces a left-handed version of this in the future for the lefties out there.
