4000 Series Ergonomic High Back Chair

For the small price difference I upgraded to the 4000 series.

I've been using the Microsoft Natural Ergonomic Keyboard (4000?) for years. I've found that I need to see the keys more often and thought the old keyboard quite large. While looking for low-vision keyboards I found this illuminated model. I thought I'd never adapt to or like a flat keyboard like this but I was so wrong. This is the best keyboard I've ever used. Easy strike, silent, and I can see the keys without bright room lighting -- even without my glasses! A full numbers layout, easy extra function keys, great configuration, easy setup, and a sophisticated appearance. Love it. Highly recommended for everyone at all skill levels.

Great chair. Takes a few days for the smell to go away. Back pain is gone. I'm able to sit long hours now. Best best best chair I've had so far. I've returned 2 chairs from Office Depot and Amazon.

Before owning this I had a Kopul 4000 series XLR cord, and maybe I got a dud or maybe it's just lower quality, but it would crackle and make noise when I moved the chord. But that is NOT the case with this cord at all. It literally works perfect. I hear NO feedback at all, no cracking at all, and nothing when I move the cord. Super super happy with this!!

Clean design, sturdy and small footprint. Used with 19 Samsung 4000 series screen.

The best looking 4000-series GPU out there, without question. Very minimal but classy. Keeps cool too, sharing a case with a 7950X and I don’t think temperatures on this card has went above 74° under full synthetic load. During productive work or gaming the card runs even cooler. No coil whine, and is super quiet. Fantastic work Asus, keep this product line going.

I will buy Kopul 4000 series cables from now on and save a lot of money over the big name brands.

This is a very nice APU. A decent upgrade over the 4000 series in terms of CPU power but not much better in terms of graphics. The graphics are comparable with the 4750G and the 5600G with a slight edge to the 5700G(2-3% maybe). Close in CPU performance to the 5600X. These APU's share the system memory so get the fastest memory you can pair with it.

I appreciate great cables. These are all I can imagine ever needing. I also use and like the Kopul 4000 series cables, especially for shorter cable runs. But these 5000 cables are reliable, quiet, and give me incredible recordings. They resist tangling too. I use them with condenser and dynamic mics on everything. A terrific value at this price.

I'm not testing these cables to their limits with super long runs through heavy RF infested territory, all while being tramped on and driven over. Here's what I can say... the 3000 series is mid-weight and pretty flexible; easy to wrap and so far there isn't any added noise from the cables. The connectors appear well made and the cable from end-to-end has a good feel. I really like the color options as it helps keep each source well identified. I'm using these for short RTS intercom runs, my aux run feeding IFB earpiece and line-level audio output from the mixer to the recorders / cameras. I went with the 4000 series for my actual mic runs, as mic level over a long run is more susceptible to exhibiting noise from RF than line-level signals are because of the weaker signal being amplified after the run. For comparison, the 4000 series cables are heavier, stiffer and a little less flexible when wrapping. For the price (which is very good), I think the 3000 series cables are great. I can't say whether the 4000 series will give me any real-world benefit when it comes to sound, but they do have a more heavy duty construction.
