Banggood

He arrived in St. Petersburg in 25 days. Packaged well. Excellent quality, no complaints, this corresponds to the description.

good shield, build quality is pretty good, the screw terminals are too close to the two mounting holes making them unusable though

Di buona qualita.

... however, arrived intact and decent. Quality appears quite good.

Tested it work perfect

I used these relays to build a fermentation control system using an Arduino Uno as the control board. These relays worked perfectly and they were so inexpensive! They may be causing some electronic noise for an LCD display, that gets scrambled when the relays switch on and off, but I haven't determined the actual cause of that yet. Would definitely buy again!!

Продавец обманщик. Я прождал заказ больше двух месяцев и ничего не получил. Продавец сваливает все на доставку и не хочет решать вопрос. Очень плохой продавец. Никому не советую с ним связываться. И звездочки все заранее стоят - не уберешь лишних.

I needed this to switch high powered devices using Node-MCU IoT controller. Needs a logic level converter too for reliable triggering from the Node-MCU board (3.3v -> 5v)

Excellent quality for the price. Better-than-usual soldering too. Very tidily put together, and they work faultlessly. I would definitely recommend these to anyone thinking of adding them to their project. 5 out of 5 stars!

Consgenato in circa 60 gg per un ritardo. Imballaggio efficace. Il prodotto è esattamemte come descritto. Ottimo prezzo considerando l apresenza del disaccoppiamento ottico.
