This DIY assemble kits is equipped with 6-digit LED modules. It is fun to build and also helps you develop a more professional approach towards electronics.
It is programmed AT89C2051 MCU chip, precise time display, 24 hours format, supporting seconds correction, countdown clock, stopwatch, counter, hourly chime and alarm clock functions.
High quality PCB, has clearly marked the electronics components, even beginners can easily solder successfully.
Specifications:
Operating voltage: DC 7V-12V (typical applications is 9V).
This project kit is not proper working please help me my kit

Digital Electronic Clock without Hourly Chime.
The pcb and the components are of good quality but the description is wrong as there is no hourly chime. The four leds do not blink every second and are always on. The circuit diagram does not match with the pcb routing. Pin 19 is not connected in the pcb with the leds. The leds instead are directly connected to Vcc via a resistance. Even if somebody connects a led with pin19 it does not blink as the software does not support such a function. No provision for speaker output for hourly chime. The assembling procedure is very easy and everything is marked rightly on the pcb. If assembled properly the clock works. The seconds display cannot be adjusted. Only adjustment supported is setting of minutes and hours.

Good for learners
Being new to electronics, I have immense appreciation for this DIY kit. Its fun to build and easy to assemble.
Careful, careful, no return policy once ordered, Monitor is very fragile
I order 15.6 inch monitor with built in stand for my Raspberry PI. The issue with built in stand, is that it is so fragile that a slight movement in cables the monitor will move and it can topple breaking the LCD panel. The stand does not help monitor to be in one place, not suitable for regular use.
Be careful before ordering this product as as the company does not accept returns and has not return policy, be careful careful careful.
This is Delhi based company which is importing items from China and selling without any return policy.
Received the product in very good packaging, also the way it was inside it seems they test the display before shipping which is a great thing ensuring defective piece doesn't get delivered! Very fast delivery. Highly recommended!
