TECKNET Ergonomic Mouse, Wireless Rechargeable Vertical Mouse for Carpal Tunnel Right Hand, 4800 DPI 5 Adjustable Levels 2.4GHz with USB-A Receiver, Silent Click, for Laptop, PC, Desktop (Not USB-C)

Great Product
It’s a cheap, comfortable, and functional ergonomic mouse. Overall, great product.

Pretty decent and generally silent, but a few minor issues
First of all, I’m comparing this to my old mouse, the Logitech MK550.• Sounds: The left click is truly much more silent than the MK550, but the right click is still somewhat audible (though it’s still about 50% softer than the MK550). Unfortunately, the forward-backward navigation buttons on the left side are not silent at all, and they are about as loud as any other mouse, if not louder. When scrolling, the center scroll wheel is slightly softer, but the sound from pressing it down is louder than the MK550.• Size: Dimensions are slightly smaller than the MK550, but comparable. The product specs list 107 x 63.5 x 39 mm (4.2 x 2.5 x 1.5 in). It’s also fairly light.• Batteries: This only takes 1 AA double (not included in package), while the MK550 needs 2, so that’s a plus. Not sure how great battery life is yet, since I just received this product, but hopefully it’s true to the advertised 18 months.• Ergonomics: The MK550 has more pronounced grooves, so it fits your hand a bit better than this Tecknet one, which has less dramatic curves and sort of resembles a large cowry shell. The MK550 also has slight indentations in the left-right click buttons, while the Tecknet does not (again, it resembles a smooth shell).• Additional: DPI/Mouse sensitivity center button is nice to have, and it seems to be working properly. The aesthetics are fine – it looks like a nondescript mouse you’d see in any corporate office or school setting. Price-wise, this was under $9 for me (I got a coupon clipped). Installation was an easy plug-and-play, as all contemporary mice should be, and the instructions manual was written in proper English (note: I really don’t think you need an instructions manual for a mouse, but frequently, when I do buy a product on Amazon that does need some information, the English tends to be grammatically incorrect or just difficult to understand, so it’s a nice bonus that the instructions are so straightforward).So in general, it’s a great budget mouse that will serve your needs and mostly fulfills its primary selling aspect, the silent clicking (but again, only if you’re considering left-right clicking, which I assume will be most of your mouse utilization).UPDATE – 11/20/2021The battery I used for this mouse just died last night. The battery I used was a completely new Duracell Optimum battery (the one that looks like it has stripes around it), which I picked up from a random store (I think it was a CVS). So anyway, that means the battery lasted almost exactly 5 months for me, not the advertised 18 that it says on this description. Additionally, I work from home, so I’m constantly on my computer. Perhaps my battery wasn’t great in the first place (though Duracell tries to market their products as the best…). Regardless, I never really believed the 18 month statement anyway, especially with my usage, and 5 months isn’t too bad. Just wanted to include this additional heads-up.

Wireless mouse
This mouse works great. It is comfortable to hold and maneuver. Overall, I would say it is great product for money.

Quiet beeping and cursor speed
Nothing wrong with how it feels, but the cursor speed I want is right in between two settings so it’s either a little fast or a little slow. Also, something that really drives me crazy is a veeerrry quiet beep that the mouse makes when you move it. So I’m going to return it for that reason. If you have any music playing or headphones on though, you won’t hear the beep.

La scheda di rete del mio portatile ha iniziato a dare problemi per un falso contatto nella presa integrata (dopo quattro anni di attacca e stacca ogni giorno), fortunatamente questo dispositivo mi ha permesso di risolvere la situazione in maniera eccellente.La rete è velocissima (è un 10/100/1000) e per farlo funzionare su Linux Ubuntu 14.04 non ho dovuto installare nessun driver, semplicemente tolto dalla scatola, inserito nella porta USB e attaccato il cavo di rete, va che è una bellezza.In altri commenti lamentano che l’oggetto ricevuto è diverso da quello in foto, probabilmente hanno preso il modello senza porta di rete perché questo che mi è arrivato è perfettamente identico.E’ solido con scocca in alluminio anodizzato, è di ottima fattura ed ogni componente è ben salda all’altra.Le prese USB sono molto buone, le spine si inseriscono senza difficoltà e restano ben ferme garantendo un buon contatto.Il cavo USB forse è un po corto (circa 20 cm inclusa la spina), ma allungando il cavo diminuirebbe la banda quindi la velocità di trasmissione dei dati, perciò è ragionevole che sia così.Poco sopra alla prima porta USB c’e’ un forellino da dove filtra la luce di un led blu che si accende quando il dispositivo è collegato alla porta USB del computer, mentre per la rete ethernet non è presente alcun led di segnalazione.In definitiva lo consiglio vivamente, funziona bene senza dover installare alcunché, la qualità dei materiali è ottima ed il prezzo pagato (16,99 € con spedizione Prime inclusa) appare più che onesto.Un applauso alla logistica di Amazon che ha battuto se stessa consegnato in un paese di provincia in meno di 20 ore dall’acquisto.

Well-made item with a choice of Bluetooth or wifi (via a supplied usb dongle) connectivity to your laptop. I use Bluetooth and it worked immediately and seamlessly. There is a nice ‘dpi’ feature via a button click which changes the resolution of your mouse positioning to accommodate fine movement (e.g. for detailed drawing) up to rapid sweeping across ultra-wide monitors without requiring long-distance mouse travels. There are a couple of buttons on the side for forward/back browsing as well as the traditional left/right and clickable scroll wheel on top, and all fall neatly under fingers/thumb and give a positive response. Easily as good as other devices costing twice as much or more.Battery life seems good too – over a week of office-style 9-5 use – although there is no indication of charge level until you get very low, when a red warning light appears.

soundless and super comfortable
