Slimmest & Most Discreet Recording Pen on The Market

NOTE: Pen cap mention in video above is an optional accessory.

Introducing the newest version of our popular SL100 voice activated recording pen. This is the slimmest and most discreet voice recorder pen on the market.

The SL100 recording pen writes with real ink and fits very comfortably in your hand making it great for meetings, lectures, and memos. The recording function is super easy to operate; simply slide the pen clip down to start recording and slide back up to stop. There are no buttons, confusing lights, or sounds associated with operation.

With the voice activation feature turned on you can set the pen to record only when there is audio present (the recording is paused during times of silence). You can listen to your recordings from the pen by plugging headphones or speakers directly into the top of the pen or download recorded files to any MAC or Windows computer.

    Good voice recorder and hardware playback

    This pen has good voice recording and playback when you use the hardware interface. The only complication may be plugging the pen via USB to a Windows computer. While the manual indicates the pen should be identified as a specific type of device, when I plugged in the pen I got the "usb device not recognized" message. After contacting support, they let me know that they do not have any type of windows driver for the pen. If you have no intention of plugging in the pen to a computer then it should work fine.

    As advertised!

    I have the Slim SL100. Easy to use, works as advertised, and super sensitive to sound. Great product and well worth the money. The directions in the box were somewhat dated but the website had the latest version. I recommend to company also sell a similar looking pen that's not a recorder that could be substituted in sometimes (just an idea).

    MQ-77N Digital Voice Recorder & Pen

    This is the best recording pen! It will record high quality audio for 12 hours with power to spare! It is comparable in size and shape to an ordinary pen. You can play back and manage files without a computer! It will store up to 140 hours of audio in up to 99 files. That's not all! It has volume control! Hook it up to a portable speaker and you can play back audio for up to 8 hours! It will blast audio volume to the capacity of the speaker!!!!!!!!!!!!

    Awesome product!

    A true life saver when you need the facts. This will pick up even the smallest sigh. This has been invaluable to me. I have purchased a total of 3 pens! I'm a happy return customer!!

    A must, to protect yourself these days.

    It worked great, clear with little background noise.
    I could not believe how well it worked. Even in my pocket.

    Great, BUT . . .


    1. Unbelievable quality & sensitivity for recording.
    2. Great battery life & storage capacity.
    3. Nice-looking pen; a bit thicker than the average pen but not so much as to arise suspicion.
    4. Easy to download files to a PC.
    5. Good customer service.


    1. No internal time clock ==> NO time stamping of recording files. Best to download your recordings often so you can date them.
    2. BIGGEST FLAW: A major design anomaly from an otherwise well-designed pen - the chintzy PLASTIC clip that is used to both secure the pen in your pocket AND turn the recording function ON/OFF. It is so cheaply made, it falls out of my pocket each time I bend over. Also, it actually broke on my first pen (the older MQ-77), so I had nothing to hold it in my pocket. Ended up dropping (and losing) it somewhere - a very costly loss. Even an inexpensive $7 Parker ball point pen has a matching stainless steel clip that has spring tension. Why a pen that cost nearly $200 can't design a better clip is beyond me. I'd check this feature before ever buying another one.
    3. The lack of the optional cap makes the pen suspect as a spy pen. For the price, two or three should be included & should NOT cost $3.95 each. If you plan to record without being noticed, GET the cap!

    SUMMARY: GREAT for recordings! Swallow hard to accept the design/marketing chintziness.
