Easy to install
Installed on a gate motor, works great, with the wiring diagrams for the boards installation was easy. Instructions are sufficient considering I never did something like that before.

Nice product. Well built. But, there's a problem.
The rating is mostly for the board. The 5th star would have been for the app. The hardware looks well done. What isn't good about it as a system is the app. It is a blatant opportunity to copy what's on your phone. What does a switch need with my personal info, photos, videos, and other non-requisite items to control a SWITCH? If I cannot find an app that doesn't do that, I'll return it. But, hey, if you don't care, go for it.

Only bench tested so far but I really like what I'm seeing.
Only bench tested so far but I really like what I'm seeing. Easy set up. Quick response to on/off commands. Power draw is low but not low enough for what I was hoping to do with it. Measured power draw: Paired to wifi and in standy mode (relay off): 70ma Paired to wifi and in on mode (relay on): 140 ma Because I wanted to power this with two 18650 batteries rated at 2400 mah together, the power draw is too high for me to use these. They will come in handy elsewhere most likely. Ended up going with a different wireless relay, one that uses at 433mhz remote, not wifi. Much lower standy power.

Not a robust product
The 2 units I ordered started out working just fine. One stopped working after about a month. The blue led light barely flickered on the one that stopped. The unit is shorted out, checked with a volt meter. The other unit was used with the same power supply that the failed unit was using and works just fine. Needless to say, the product doesn't seem to be a very robust design. I tried to send it back but Amazon doesn't seem to have that option. Getting product support as far as a replacement doesn't seem to be supported

電動シャッターの遠隔での開閉用に使用しました。セットアップもアレクサ連携も簡単にでき、使用感も良好です。

Aunque no muy buena documentación como la típica de estos productos, el producto se programó fácilmente y se enlazó muy bien a la red, la operación resultó muy buena y a la fecha no ha fallado, yo la tengo para abrir una puerta eléctrica y lo hago con Alexa sin problema, sería muy recomendable que tuviera una carcaza, tiene las medidas idénticas que las de un switch de otra marca y utilicé la cubierta de plástico para poderla instalar con alguna protección.
