Not sure why the power button does not work at all. I can only unplug to cut power...I bought this for the power button specifically.

Maybe defective switch or you have short somewhere on your flight controller. (Red light) Reason for power switch is for Power ON/OFF Switch for Easier Receiver BindingHolding down the bind button and applying power can be challenging sometimes. The new version of VIFLY ShortSaver added a power on/off switch that can make your receiver binding much more convenient Try smaller 3S Lipo battery because this sometimes gives me false alarm by using 6s Lipo This short saver is very sensitive to power surges It may tripping it off Sometimes it makes me think there is short somewhere in my build.

What is e-fuse? Any difference from other smoke stoppers on the market?

Almost all the other smoke stoppers on the market are light-bulb or resettable fuse, the biggest issue of them is the current leakage and slow reaction time, it has the potential risk to damage your build. VIFLY ShortSaver 2 use the electronic fuse that can cut the current completely and its reaction time is much faster, it is the most reliable smoke stopper.

Worth its weight in gold.

Works as directed, takes away that first boot up, or hard crash anxiety, because you can never put the smoke back where it came from after it made that wonderful sound. Great product, great price, great quality.

Prevents magic smoke

I use this for first time powering up of equipment (such as fpv drone) just in case I've wired something wrong or have a short. No one wants to see smoke coming out of their circuits, and these prevent that from happening.

持っていて安心。FPVビルドの“保険”！

FPVドローンを自作している人なら必須レベルのアイテムです。はんだ付け後、通電テストのときにショートして機体を壊すのが怖くて購入しました。このVIFLYショートセーバーV2は、XT60／XT30コネクタの両方に対応していて、差し込むだけで簡単に使えます。電源を入れた瞬間に異常電流を検知すると自動で遮断してくれるので、本当に安心。一度使うと、これなしで電源を入れるのが怖くなるほどです。まさにFPVビルドにおける“保険”のような存在。持っていて損はありません。
