Solid Performance for My Dash Cam
I needed a reliable card for my dash cam that could handle constant overwriting. This card has been running for few days straight in 1080p without a corruption issue. It handles the heat of being in the car all day perfectly. Highly recommend for security or dash cam use

Great 32 GB Memory Card – Works Well with my Drone
I got this 32 GB High Speed Micro SD memory card for use in my S-156 drone controller. The drone had an 8GB card included but I found its capacity to be tool small. This new card quadruples my storage and performs very well. Simple plug-and-play. I had no issues with it. I may get another for use in my dashcam as well.

Pause function not working in Voice Activated Mode.
Pause button function not working in Voice Activated Mode. It’s a bit inconvenient when I choose to pause while in voice activated mode I have to do a long hold Press of the button and then I may forget to turn it back on. Voice Activated Mode works fine. I’m wondering if there is some special code that I can put inside that text file. Otherwise seems great I haven put it to use in action, i’m a contractor and I’m dealing with a very difficult customer but I also have a vacuum running throughout the day and I was hoping to leave it on all day in voice activated recording mode.

Works poorly.Don’t download software! it will kill your phone!
Diffucult to make it work. I will work with it before I state a final resolution. Right now. Not happy. I don’t give up until it is not practical to work. I will post another review later. Better to not eviscerate a product after some effort to make it work.Fortunatley I backed my phone to the cloud and was able to restore it. their app was still there. I was able to delete it. Root your phone if you have the extpertise. you can kill processes, and delete application trees when the base user O/S will not let you. It takes a bit of Unix knowledge, Otherwwise this rogue app would have destroyed my phone.

一見するとどこにでもある一般的なボールペン。ですが、その実態は「小声での会話もハッキリ残せる」ほどの高感度マイクを搭載した、非常に実用的なボイスレコーダーです。実際に使ってみて、「ここが使い勝手がいい！」と感じたポイントをまとめました。〇 「本物のペン」として長く使える安心感替え芯付きが嬉しい ガジェットにありがちな「ペンとしてはおまけ」というレベルではなく、交換用インクが付属しているため、日常的な筆記具として末長く愛用できます。さりげないデザイン デスクに置いてあっても、胸ポケットに差してあっても、誰もこれが録音機だとは気づきません。相手に威圧感を与えずに記録を残したい場面では、これ以上ない武器になります。〇 驚きの録音・再生パフォーマンス「ささやき声」もキャッチ 感度が非常に高く、小さな声もしっかり聞き取れるレベルで録音できます。メモ代わりの独り言から、大切な会議の議録まで、音質的な不安はまずありません。手持ちのイヤホンがそのまま使える 付属のアダプタを使えば、普段使っている3.5mmジャックのイヤホンで即再生可能です。専用の特殊な機器を持ち歩く必要がないのは、移動中などのチェックにとても便利です。△ 知っておくべき「管理」のルールデータの削除はPCが必須 本体のボタン操作だけで録音データを消去することはできません。「削除したい時はPCに繋ぐ」というひと手間が必要になります。アドバイス： 「操作がシンプル（録音ボタンしかない）」ことの裏返しでもありますが、大事な録音の前に、PCで空き容量を作っておく習慣をつけるとスムーズですよ！総評「録音していることを意識させたくない」というニーズと、「しっかり録りたい」という性能、そして「普段使いのペン」という実用性。これらが高いレベルでまとまった、非常に完成度の高い一台です。

Keeping track of long meetings is much simpler when a dedicated audio device is available. Pushing a single button starts recording immediately, capturing voices from across a large room. The backlit screen helps navigate menus and files in low light environments. Playback sounds sharp due to internal noise reduction technology. Internal memory offers ample space for keeping weeks of important conversations. The lightweight build fits into a small pocket unnoticed. Transferring files to a laptop works flawlessly without needing extra software. Battery capacity holds up well during continuous operation. Voice activation mode saves storage space by only running when someone speaks. The metal casing feels durable enough to survive accidental drops. Recharging happens fast through a standard port. A built-in microphone picks up subtle details clearly. Every file remains organized and easy to access later.
