  • When I read the reviews on this keyboard I was skeptical it was really that good. I was also concerned that it wouldn't work for gaming. This is without a doubt the best keyboard I've ever used by a long shot it just feels incredible. Don't waste your time looking elsewhere this is the one just order it and be done.

  • Purchased the Leopold FC660C Silent and couldn't be more happy or satisfied with the product. The keyboard itself is of very premium quality, the PBT keycaps are a dream to use, having great resilience to sweaty and grimy fingers. The silent Topre feel is like nothing else and is absolutely sublime, pricey compared to other keyboards but worth every cent!

  • I first bought a blue/grey (Silent 45g) version of this and then followed up with x 2 black ones ( also Silent 45g). One for me, one for a friend.

    This is hands down the best keyboard you will type on. Stop the modding and lubing rabbit hole, and buy this board.
    You will get used to the layout, you will love the sound and you will scratch the premium keyboard itch you have.

  • Upgraded from a Logitech G710 I purchased about 4-5 years back. The difference between the Topre silent switches and the Cherry MX browns is impressive. Value may be debatable, but this keyboard has amazing stabilizers, is extremely quite (I didn't expect to enjoy the change this much, especially with open back headphones), feels great to type on for extended sessions, and has an amazing layout that gave me back a ton of desk space. The black color scheme and subtle key legends also make the board look very sleek allowing it to be used basically anywhere. I've used it for gaming as well and personally find the tactility increase to be great, although some people may claim that browns are better because they feel more like a scratchy linear switch. I'd highly recommend this board to anyone who plans to purchase a keyboard that is looking for a highly versatile and high quality product.

  • Purchased with Silent switches to use at work. Outstanding typing feel, build quality, and is very quiet. Would definitely recommend this over a HHKB if you're after a smaller Topre board.

  • Amazing keyboard! Really. I've buyed w/ silent switches ( 10$) and insanely happy.
    Thanks a lot, MechanicalKeyboards!

  • Fantastic keyboard. Great build quality and the purple switches are just insanly good. I do recommend lubing them to make it even better but besides that its great. This is for me the best topre board. Gonna lube this heavy-6 case hasu controller and then I have my personal end game.

    Experience with mechanicalkeyboards.com was good. Do recommend buying it here!

  • I love this keyboard. I also have a WASD V3 with Cherry MX brown and 40mm O ring dampeners. While that keyboard is good, this Leopold FC660C is just incredible. The build is solid and compact. The keycap feel is fantastic. The silent Topre 45g switches are as about as quiet as the standard Apple keyboards. I'm super happy with the feel of these switches.

    I thought the missing tilde key would make using this on a mac be a pain but I just remapped cmd esc with Karabiner and was good to go. I remapped those dangling insert and delete keys to volume control so they're not useless. I don't have the rattling problem that another reviewer mentioned.

    Another standout thing with this Leopold is that the spacebar doesn't make the horrifying noise that most of the other mechanical keyboards do. It's not as quiet as the main keys but it's still relatively quiet.

    MechanicalKeyboards has good support too. I emailed them about a shipping question and they got back to me promptly.

  • Best typing experience of my life. Solid board with a nice weight, and a nice feel to each button press that makes you want to type more (currently using topre 45g silent). Can't wait for a full sized version with silenced topre to come out!

  • Get this board. You will not regret it.

    The silent switches for 10 extra dollars are a steal and make the board an grand experience.

    Mechanical keyboards 10/10. 10/10 experience overall.

  • I picked up the silenced version of this keyboard. It's the best keyboard I've ever typed on, stock or otherwise. Not a gamer, so I can't speak to that, but as someone who writes 2-3K words per day, and occasionally up to 10K, this baby is a life-saver. Just enough tactility and force requirement to keep me accurate, but soft enough to keep my wrists from hurting, even after typing for hours. And the silence switches are lovely--maybe too quiet for someone who prefers some kind of auditory feedback, click, thock, or otherwise, for someone like likes a quiet typing experience, this is hard to beat. I have mod-silenced other keyboards in the past, but I don't think I will have to do anything to this one. Never thought I'd see the day that a stock keyboard would become my daily driver.

    Only downside is the useless (to me) insert key, lol. A hasu controller can fix that though, easily enough. But this is the only topre in this formfactor that is silenced out of the box and doesn't have the HHKB layout and cheap toy components. Built like a tank. Types like a dream. What else can be said? I'm typing this review out just because I take any excuse to type on this bad boy. Love it to death.

  • This keyboard is amazing. Highly recommend. If I had to keep just one of my keyboards I think it would be this one. The keys feel tactile but not fatiguing. They have a nice thocky sound to them. A little bit of rattle to the stabilizers but I haven't really done anything to mitigate that (Lubricating) and it's not annoying to me. I have the beige version which has a nice retro look to it.

    The functionality is just what I need w/ the dedicated arrow keys. The fn arrow keys makes it just as useful as a TKL (- the function row). Fn Up/Down/Left/Right = pageup/pagedown/home/end. It does not have media keys, but if you use windows, it took me maybe 15 minutes to figure out how to map volume controls to ctrl up/down/left for volup/voldown/mute using AutoHotKey. I did miss function row when using AutoCAD initially, but then I remapped the commands within AutoCAD to Ctrl functions and now it's not an issue. I pair it with a realforce 23U for when I really need a number pad.

    Compared to Realforce RGB the typing experience is much better even though it's the same "switch"/45G dome. Hopefully one day I will be able to compare to the HHKB Type S and Realforce 87U 55G but unfortunately $$$ < Infinity. I'd say I prefer it over those two layout-wise because you get the compactness of a 60% board with most the functionality of a TKL.
