Perfect Beginners’ Soldering Project!
This soldering kit was really fun to put together! I did so with my sister, who is just starting out soldering, and it was just about right for her skill level. There is a variety of resisters and capacitors, a transistor, and a couple of other parts, including a surface mount battery holder. This was fairly large, and quite easy for beginners to work with as well. The only issue that I had was that the assembly instructions were sent to me via amazon support message stating that an error had occurred with my order. The link to the instructions pdf was a short hyperlink trail from that. Once found, however, the assembly instructions were easy to follow and very helpful. Again, though, it would have been easy to miss. They should at least include a QR code in the packaging that takes you to the pdf online. Now, while the assembly was fun and straightforward, the usability of the clock is not so great. The UI is composed of two buttons and a 4 digit lcd, and there are way too many features packed in. This makes for an unnecessarily complicated setup, and I was unable to figure out even how to set the time in the five or so minutes that I attempted to do so... Granted, I was in a hurry, and when I get back to it, I don’t doubt that I will figure it out, but the confusing experience did leave me a bit annoyed. On the plus side, there is a small battery onboard that keeps the time, so you don’t need to worry about keeping it connected to power. Overall, as a useful clock, it does leave something to be desired, but I don’t think that that was ever the intention. As a soldering practice kit though, this is a great beginner project, and I would definitely recommend! The clear housing makes for a great display piece, and it’s fun to be able to say, ‘yeah, I made that!’

Excelente para practicar
Excelente para practical, optional tener una punta Delgada pero no indispensable. Las instrucciones son claras. Necesitarás una lupa para poder soldar bien.

Very very TINY tip needed
This is SMALL...so you need to practice and have the right tip. Not great for a first or second project

Great Beginner Kit
I was really surprised at how well this turned out. It was my first ever board soldering experience after just doing some soldering on a practice board. Components fit well and only one area on the board had a tight small bit of space to fit the soldering iron. But everything went together just as the easy to follow instructions said they would. The clock has so many functions it takes a while to learn the many things those two little buttons can do. No missing parts, but no extra parts so if you lose one of those little components you better have some spares available. Overall I would definitely recommend..
