Nice product, working as intended. Currently driving an ESP32 alongside some 5v aRGB Leads. The inputs are connected, so while you are using one as input, the other can be used as an output for supply village.

It's a nice mount, compatible with a wide range of smart phone, and all standard camera stands. It has very strong springs, which can hold your phone tightly, but a bit hard to pull open. Perfect for long exposure night shots or time lapses.

Nice product, please note it is a digital sound sensor (meaning it can output 5v or 0v depending on sound level), but can be hacked to be used as an analog one

Bright LED light, sadly, I didn't have time to test it with plants, but I think it would work okay. My only issue, the strip heats up after a while, so you have to stick it to a metal surface to dissipate heat.

Great tool, really easy to use. Although you need to use it two times on each cable pin (opposed to an all-in-one tool, where one use is enough), it crimps the pin better, and the cable always fits the header. It can be used for both JST and Dupont connectors.

These relays are really good, and they are equipped with optocouplers, which is essential to switch high voltage with microcontrollers. I'm happy with the purchase.

Nice little microcontroller, easy to program and use. Due to it's small size, it can fit almost anywhere, good choice for projects where space is limited. The variety of pins included is a great plus.

Thankfully, it's working as it should be, driving a dc motor with digital pwm signal. Not the smallest module, but can handle 12V and more.

Well, this kit is a good choice if you want to start with water cooling. My experience so far: The pump is a little bit loud (maybe poor bearing), it has mixed metals (alu radiator and copper CPU block), so without proper additives, it can corrode easily over time. I replaced the fans, so I don't know how they perform, judging by it's material, it's performance might be close to the pump (like it's working ok, but a bit loud). The CPU block was the right size in terms of the mount holes for my i7, but sadly, it couldn't reach the CPU itself (some capacitors were in the way, I couldn't lower it enough. Fittings are really nice, you can connect the pipe tightly, no dripping. The tube is long enough to connect everything (around 2m). Tank is okay, but the plastic mounting brackets are useless. They can scratch your tank really bad, but won't hold it. For me, screwing the pump tightly, and connecting the tank directly to it was enough. How it'll hold out, time will tell...

Radio arrived on time, it works really good with Liftoff simulator. It has red stick caps, not the silver ones shown on the picture. Built-in 18650 charger works as well, but the battery holder was a little too big for my 18650 battery (bending the connector plates carefully could solve the problem). It is worth to check out set-up and config videos on the net, because the included user manual is not too informative, and it is full of typos. The indicator led can be too bright/annoying in darker scenarios.
