Customer Reviews
Good value, nice keyboard
I was looking for a new mechanical keyboard and saw Knewkey. Got the DJ88 during a sale and felt it was a solid deal. The discount made it worth it, especially for the features. Shipping was alright, took about a week to get to me. Overall, happy with the purchase.
Consistently good quality
This was my third time ordering from Knewkey, this time I picked up the Wood Grain Mechanical Keyboard. Each experience has been smooth. My first was an RDJ4 and the second was a set of PBT Keycaps. They always deliver on time, and the product quality is consistent. No issues with connectivity or performance with any of them. It's why I keep coming back when I need something for my setup.
Keyboard arrived quickly
Needed a new keyboard and saw the RDJ4. Placed an order and it got here faster than I thought, maybe 5 days to Denver. It's a nice keyboard, feels good to type on. Happy with it.
Love my new keyboard!
My new Typewriter Style Keyboard is fantastic! I've been wanting one of these for ages. It looks incredible on my desk, and the sound of the keys is just perfect. Connecting it to my computer was super easy. I'm so glad I finally got it. This keyboard makes typing fun again! Definitely a great buy.
Detailed RDJ4 Plus review
I ordered the RDJ4 Plus a few weeks ago. The ordering process on the website was straightforward, no real hiccups there. Delivery took around 8 days to reach Texas, which was within their estimated timeframe. The packaging was secure, and the keyboard arrived in perfect condition. I was particularly impressed with the build quality; it feels very sturdy and the retro design is exactly as pictured. Connecting it via Bluetooth to my iPad was simple, and it works great. I did have a quick question about switching between Mac and Windows modes, and customer support responded to my email within 24 hours with clear instructions. The keycaps have a nice feel, and the switches are satisfyingly tactile. It's a noticeable upgrade from my old membrane keyboard, both in looks and typing experience.

Thinking of getting an RDJ4, but worried about shipping to Chicago. How long does it usually take for US orders?
Anyone know if their keyboards are actually hot-swappable? Want to try different switches but don't want to solder.
