This project is very straight forward. There's not really any directions, it's just a parts list and a blurry schematic, but that's alright because everything is pretty self-explanatory and each part really only fits where it is supposed to go.
I bought this as my first solder project. I thought it might be a little difficult to tackle as a first project but I wanted to at least try to make something practical, instead of one of those kits that simply makes an LED light up with no other use and then gets thrown in the trash.
I have never soldered anything before, but I did have an idea of the basic process because I have seen videos of people soldering. I was able to complete this entire project start-to-finish in about 2.5 hours and I had fun building it.

Easy and complete kit; recommended
This went together very easily for me. Took a few relaxing hours, the kit had everything needed, and the assembly was straightforward. Finished product is a usable basic math calculator. For the price, I'd rate it as great value. The PCB is clearly labeled for all parts. It's so intuitive, I think you'd have to sort of deliberately try to put it together wrong. In fact, the case assembly was more difficult than the electronics assembly. Neither was very difficult. The kit includes the PCB, 17 keys (base, label, two-part clamshell pad), battery holder, micro-USB power jack, single capacitor, single IC with socket, and two 3-digit LED displays. If I counted right, that's 126 solder connections, all but two are through-hole. The component that uses two surface mount points also has two through-hole points. Then there are four board standoffs with nuts, four board mounting screws, and four case assembly screws with nuts. The case itself is four sides (each unique shape), and a top and bottom. The kit also comes with a CR2032 coin type battery, but the one in mine was dead. And a pre-printed, color, slip of paper that you can cut up to use as key labels. To assemble, I used a soldering iron and solder, wire cutters (only for the capacitor), and a tiny Phillips screwdriver with needle-nose pliers for case assembly. Oh, and scissors to cut the key-label papers to size. Once assembled, the unit appears to be quite durable. The keys press with definitive tactile clicks. I have not run through testing of the resistor color band function, but it does basic math functions correctly (+, -, *, /). The display is 6-digits provided by two 3-digit LEDs placed side by side. The displays are bright and easy to see. The chip does have a lo/hi error function that displays briefly on over/underflow, and then it shows the truncated result. One quibble on the case - and it's minor - the assembly screws stick out the back by a millimeter, so the completed unit won't be friendly to scratch-able surfaces. As a kit? Great! As a good desktop calculator? Well... there's always pride of assembly, right? And it's quite distinctive looking.

Pretty fun to build, but the stands don't reach the bottom so the PCB isn't fully secured. The buttons had paper that I opted out on, since the numbers are on the board. The instructions were miniscule but the wiring diagram was easy to follow.

As others pointed out, there are no instructions. The qr code included just takes you to the merchant's Amazon store.
I assembled and soldered carefully but it doesn't function.
I do not recommend this kit. You are risking throwing your money and time away.

Entry Level Project.
Approximately 1 hr to complete.
Nice easy project for a student or anyone getting into electronics and soldering. Calculator is handy in identifying the ohms value for resistors. Still recommend spot checking with a multimeter to make sure they are correct but definitely a fun, easy, and handy calculator to have for DIY soldering projects. Comes with a nice case too.
Also, does regular math for +, -, /, and * with a 6-digit display screen.
