Perixx PERIBOARD-505H PLUS US, Wired Mini Keyboard with Trackball & 2 Hubs - USB - 14mm Optical Trackball - Build-in 2xHub - 1.80 M Cable - Piano Black - Fit with Industrial or Professional Use - US English Layout

I got this keyboard because I wanted a small integrated keyboard & pointing device for use with some servers that don't normally have a keyboard attached. This keyboard is great for that - very light to move around, no batteries (USB), an integrated trackball. The trackball is a little bit oversensitive when used in environments like a computer BIOS where you can't adjust sensitivity, but in general it works great. The keys have a very short travel but are comfortable in use. The keyboard is probably a bit too small for regular use, but it's perfect for what I wanted.

Functionally great, was looking for a keyboard with built in USB sockets so I could add memory stick directly and or a mouse without bending over every five minutes. This works great. It also has a track pad which is useful, if a little oversensitive. The keyboard itself is a little cheap in feel, I'd happily pay another £10 for more quality feel but so far this keyboard serves its purpose.

I bought this keyboard as I wanted a wired keyboard with a built in trackball that would work with the Raspberry Pi device. The fact that the keyboard has onboard usb ports and has a small footprint are a bonus as well. Thankfully the keyboard and trackball work well with the Raspberry Pi - recommended for anyone looking for a smaller keyboard/trackball combo for this device.

There was lots of research involved, before I stumbled across this little gem. My criteria was to purchase a mini keyboard that wouldn't dwarf my 22" smart TV when not in use, and would comfortably sit on my lap when in use; so I didn't want a mouse - no where to roll it, so the trackball was a great little addition! And I wanted the extra USBs for future computer gizmos. So this was a great find...would highly recommend.

Although sold by Perixx UK on Amazon.co.uk this keyboard has the wrong keyboard layout for UK computers. The backslash key ( \ ) which is a very important key in Windows networking and file paths does not work. It is located in the wrong place above the ENTER key and if you use a standard UK keyboard configuration which is the norm you will have no backslash key and other keys are wrong too. I emailed Perixx who simply told me the backslash key is next to the Z key which it clearly was not. They did give me a work around to install the USA International and use shortcuts to access the keys but really it is a major PITA!!! Why 2 stars? Well it is a nice compact keyboard and the roller ball and mouse button work well and it seems an OK keyboard for the price so 2 stars for the pluses but 3 stars off for selling me the wrong keyboard in the first place. I mean come on Perixx and Amazon both, how hard is to figure UK customers want UK keyboards and NOT American ones? Pffft

No numlock key. Keys with Fn not indicated. Sometimes USB loses touch with PC. Other than that, very good to use

Great product does exactly what it says on the tin. Nicely made, works well.

The trackball is very small, which I was prepared to put up with, but it doesn't work. It worked for about 20 minutes and then started getting stuck. Really rubbish considering the £20+ price. I am a programmer and have used a Logitech marble mouse for years. THAT is a great trackball mouse. This KB is not. Don't waste your money.

La tastiera è ben costruita e funziona ottimamente. Per un uso professionale può far piacere sapere che il trackball è posizionato nell'angolo in alto a destra e si tratta di una sfera abbastanza piccola (inferiore alle dimensioni di una pallina dei vecchi mouse), con una velocità di rotazione elevata (cioè fa poco attrito). Questo consente spostamenti velocissimi del cursore.

Good keyboard. I wish they swapped the left alt and FN key. I wish the roller ball had a quick release to clean the dust. I wish it had a scroll wheel

Perfetta alle mie esigenze. Trovo utile anche il trackball in caso di emergenza, anche se continuo ad usare il mouse

トラックボール付きのものを探してたところ、こちらが安価で11inchタブレット用のバックにも入るサイズでしたのでこちら購入しました。初英字キーボードでキーの配置が若干違うことへの慣れ、日本語入力切り替えの設定変更など必要そうです。押し心地はなんというか90年代のパソコンに付属してたものに近いです。トラックボールは若干反応悪いです、ゆっくり転がすと動かないです。 たまにしか使わないので問題ないですが、メインで使おうという方にはトラックボールの反応の悪さがネックな感じします。

OK, so I am loving this keyboard in most ways. I love the dedicated numeric keypad, helpful as I test screen readers. I am typically a keyboard-oriented user, and the typing feel is definite, without mushiness. But the design of the trackball does pose challenges. I am not a big fan of trackball on the right, buttons on the left, but the placement of the right and left buttons is problematic, as others note. I am mostly wrapping my hand around the right corner and moving the ball with my thumb and pressing the left mouse button with my forefinger. The trackball isn't as sensitive as some others have commented, but the manufacturer may have responded to feedback. That wraparound technique is probably only manageable for someone with smaller hands, and it might not be manageable if the keyboard is in a drawer for rack-mounted systems, etc.. If I had larger hands, I could cup my hand over the numeric keypad and press the left mouse button with my forefinger and roll the ball with my middle finger. Overall, though, this keyboard is going to work best for people who aren't using a pointing device a lot. That being said, I like it better than the Adesso it's replacing. Kudos, too, for including an Applications key, when many keyboards omit them, which is hard on assistive technology users.
