Korg RK-100S Keytar 37 Key MIDI Shoulder Keyboard & Synthesiser - Black W/ Case 

Appearing in 1984, the RK-100 remote keyboard broke the chains of keyboardists, setting them free to perform as they liked. With a stylish body available in four colors, it allowed the keyboard player to challenge the vocalist or guitarist for the main role on stage.

Thirty years later, the RK was resurrected. Although beautiful curved surfaces have been added, the essence of the original and very popular design is unchanged. What had been a somewhat large and heavy body has been made more compact and lightweight thanks to modern components such as a slim keyboard. While the original required an external sound module, the new RK-100S contains a built-in analog modeling sound generator.

New features and functions include two ribbon controllers, an arpeggiator, and a vocoder, and there are also "favorite" buttons that allow you to register frequently-used sounds for one-touch selection. The RK-100S is your choice for smarter, more active, and more enjoyable performance. (KORG offical website)


The Korg RK-100S is an awesome gift for anyone who is into 80's music / keytars. The MIDI out function means you can use this unit with your other MIDI compatible synths / sound modules. This unit would also be great for a retro inspired video clip or movie, to rock out on stage with or add something fun to your current set up.

Sturdy, smaller sized supply caddy-well crafted.
Size: 5 Tiers (5.1"D x 39.2"H), Color: Rustic Brown + Classic Black
Why did you pick this product vs others?: Started out asking friends what they use for a cart - to clear stuff off their drawing boards, desks, etc. I've got an unusual amount of "things" in my workspace, and although I keep paints in a separate caddy to one side on my drafting table, the topside clutter was getting unbearable. Due to people giving me things, my interest in a few crafts, and just junk. Mainly I use the my wonderful, old, 1950s school cast-off - drafting table for painting - as it tilts and I have an edge on it. I've been wanting to also replace the top board, too. The usual caddies didn't appeal to me - the plastic ones annoy me as I can't see in the bins at what I should easily be able to reach and cannot see-though the opaque plastic. As I purged the clutter I realized I needed way less than I had and that's how I determined the size of the rolling cart. I use my spare garage and I have a lot of space, but that's the kicker - the more space you have the more things you could have, too. That's my reasoning for choosing a smaller cart. Narrow, to keep it minimal. Black metal to hide dirt. Wheels? a bonus - I'll just pull it back and forth out of its space--it's not going to be a trolley. I picked this one out of several because of price, and size, but I may come back at another time to purchase a larger one for the coat closet - mittens & hats & ski goggles & stuff.  I am going to look at the same brand, but I'm also going to choose one with sturdier wheels.  THIS CART was easy to put together, no issues at all. I didn't time myself - it took a while - under an hour is my best guess due to all the small pieces. I know it was manufactured this way to be able to fit it in as small a space-box for shipping, as possible. It was tedious, but certainly not an issue. Just lay it out the way the diagrams show you - they are perfectly done. It's sturdy enough as a supply caddy - you can't sit on the thing, or let kids romp on it but it's stiff in all the right places and the handle is perfectly placed. The top of it will hold my tablet or phone - next to my table; it's not a decor piece, but the black finish does look rather nice -with the faux wood/wood laminate top. Basket depth is well thought out, too. Coffee cans with paint brushes, some other tools, but the best part is no more clutter taking up space on top of my drafting table and I can actually use it the way it was intended!

Perfect fit

I was hesitant about ordering after reading some of the reviews, however it was exactly what I was looking for. It turned out to be a good investment, however the reviews were correct about the wobbly wheels. For the $ the wheels should have been made with better quality, which would have given the product more steadiness. Overall, a good product and it was easy to put together.

Great addition to my kitchen
Size: 5 Tiers (8.7"D x 39.2"H), Color: Rustic Brown + Classic Black
This fit my odd space between the wall and stove perfectly in height and width, I just wish it was long enough to go to the back wall. I found a tall shelf to fill the gap. The look of the cart accents my decor and will continue to match after I paint my cabinets. Assembly was straight forward and easy. Took about 10 minutes. The instructions were clear. The wheels don't like my tile for some reason so I'll have to get new ones from the hardware store, something that isn't plastic. This isn't an issue for the cart necessarily, my floor wasn't the best install. This cart works well on my other floors.

I absolutely love this food storage cart!! I was tired of putting all my breads, fruits, and veggies on my kitchen counter and just happened to have this sliver of space between my coffee table and the fridge. This storage cart fit perfectly and I like that you can move it around while cleaning or cooking. It fits more than you think and you can get creative with it (like removing food from packaging, using a basket, etc). It was really easy to put together. Materials are sturdy, not flimsy, and will probably last forever. It's super easy to clean and a great value for your money. This storage cart has saved my sanity in the kitchen!
