perixx PERIBOARD-522 Wired Trackball Mechanical Keyboard, Built-in 2.17 Inch Trackball with Pointing and Scrolling Feature, US English Layout

**Update** i made a note in the review below about the small amount of static friction on the track ball, below. I picked up a tip from elsewhere online which is to get a plain candle and rub it all over the ball to give it a coating of the candle wax then spin the ball around in all directions for a while which causes the synthetic bearings to also be coated with the wax. This has made the track ball super smooth with less static friction than before. Been using this for a good 8 months now so thought it was time for a quick review. I can't quite get my head round the negative reviews on here - I've been using this keyboard for work, solidly for the last 8 months - the quality of the mechanical keys is lovely - brown switches so nice and tactile without being annoyingly loud like the cherry blue types for in the office. It's US layout, but to be honest I much prefer this to UK layout now and have switched to a US layout keyboard at home too - but be aware if you're looking / expecting a UK mapping. i bought he non-illuminated board and the keycaps are the same as the illuminated one by the looks of it - so they're properly produced keycaps where the letters will not wear off with use unlike 99% of the cheaper keyboards I've ever bought with printed caps which have been worn off completely on the most used letters over the years. The integrated trackball is, well, nothing like the usual rubbish that gets integrated into a keyboard. I was a bit worried about the button and scroll wheel placement to start with but turns out to be really usable for me. The scroll whell is "notched" not free rolling so basically like a big version of what you'd get on a mouse. I only just realised the other day that pushing left and right on the scroll wheel actually does horizontal scrolling too - probably detailed somewhere in the instruction book I never bothered to read. Trackball movement is really nice, it's up there with the big kensingtons etc - it's "clicked" into place so doesn't just lift out of the board (so the ball won't just fall out if you move the keyboard). It's optically tracked and really accurate, there's two dpi settings selectable from a function key / f9 combination but there's no indication on the board of which DPI mode it's in but I don't really change it very often. I've yet to have had to take out the ball for cleaning also seems to be really good at not picking up and accumulating dust etc. It's a lovely solid, decent built keyboard with a bit of weight to it. Will probably last years. Braided USB cable. What's more to say. Really happy with it - absolute bargain given how much you'd pay for a trackball of this size and quality and a decent mechanical keyboard if bought separately.

I found the keyboard to be too noisy for an office environmen, also the lettering hard to see in some lighting conditions.

I bought this unit for my wife as she is a touch typist. We also used to have a separate keyboard and trackball in our recording studio. This all in one keyboard and trackball, she absolutely loves it. Thank you

The keyboard works, the trackball works, but that is about it. The keyboard I got does not have a UK layout, with anoying issues like the "@" signe over the number 2., but you might like that. Not for me. The keyboard is loud - comically so. Like a throwback to the age of typewriters. No padding there whatsoever. Overall the manufacturing feels very cheap. The keys are large and clanky and very deep. no subtlety here. The trackball is a bit large for my likeing and works, but again lacks subtelty. All in all it is not worth more than £30 in my oppinion, and I do like the form factor, but it is let down by it's quality. Certainly not worth the money.

La tastiera soddisfa egregiamente il suo compito. La pressione dei singoli tasti è davvero soft e reattiva ed il trackball è comodo da utilizzare e sensibile sin dai minimi spostamenti (i tasti destro e sinistro sono perfettamente posizionati sotto la sfera e la rotella di scroll è tarata con il giusto scatto di scorrimento) Il prezzo però mi sembra un po' altino

Brilliant keyboard, tactile keys make typing pleasurable and easy on my fingers, plus the trackball instead of mouse has reduced the strain on my wrist. Not having a wireless connection is also a bonus, there's no "black spot" on my desk for this and, in the long run, not having to replace or recharge batteries is good for the environment. It's well made and feels robust, so I'm looking forward to many years with it. Delivery time was quick, packaging was robust, it arrived with zero damage and early. Can't ask for more.

Cumple las expectativas, aunque el tacto de las teclas no es agradable, eso sería una mejora significativa.

Decent value, as advertised. Pros: - Responsive, accurate trackball - Tight yet clean design/layout - Convenient scroll wheel and mouse buttons Cons - Price - Keys require a fair amount of force
