Nagged for Review, Haven't Received Order. You asked for it... Perixx marketing emails have nagged me twice to review my experience with them, and I don't have my order yet. The product is late vs. their initially stated delivery date. Maybe it's a good keyboard, but who can tell? However, I can tell their order fulfillment and marketing departments never seem to talk to each other.

Good service, good product Perixx was remarkably prompt and helpful about addressing my pre-purchase questions. Shipping was quick. The product I bought (Periboard 613) seems very well designed--as a Mac user, I love being able to make it a Mac keyboard with just a switch rather than remapping the keys myself, and I'm impresses that they include a tool for swapping out the key caps. The only remaining question is my long-term experience with the keyboard, and I haven't had it long enough to answer that.

The best value in thumb trackballs. Shipping: excellent. Product: excellent. Other thumb trackballs tend to have places where the trackball doesn't run smoothly, but I've yet to have a problem with Perixx in that regard. I got the wired trackball because its response time is faster than the wireless, making it a better choice for time sensitive input.

My second purchase and I'm quite happy… My second purchase and I'm quite happy with both products price and quality match up with what I like. Not quite as fancy as the Logitech but one third the price and it has programmable buttons if you use Windows which Logitech doesn't. I think I might be buying a keyboard next I love their ergonomical full size keyboard.

Highly recommended Small compact size fits anywhere space is limited. Large font size with backlighting makes excellent visibility of the keys. However, I wish the backlight is designed to only illuminate the letters but not create a halo around the keys that would appear more elegant and less distracting to the eyes (similar to the backlight of Periboard 326 which I also own). I also would suggest Perixx use a warm neutral white backlight instead of the bluish backlight.
