First of all I found the boards well laid out and Made of Metal is a Plus , However I wasn't real fond of the Pads , there Way to small and I had a hard time getting the solder to stick ... And the shipping time was a little too long . But I would still give 4 Stars ****
I ordered three of these hearts. They arrived rather quickly. When they shipped I received them in four days, including the weekend. I picked them up at the mailbox while on the way to orchestra rehearsal. The next day (today) after work I got to really check them out. They come nicely packed in plastic zip bags. Some of the items are in anti-static bags. Everything was in a bubble wrap mailing envelope. The instructions for putting them together are available on the description page/order page. I didn't need them, but they are step-by-step with pictures. You can't go wrong. I soldered two of them together before dinner. The circuit boards are nice and thick. They are larger than I expected, which is really nice.
I think that if you want to teach a youngster how to solder, this would be a good project for that. They would end up with a nice gift for mom, grandma, or that special person.
I am going to order a few more because I like them that much. I gave one to my wife tonight. She really likes it. My niece was visiting and she thinks it is a great looking piece of art.
I bought 2 pieces of Beaglebone Black protoboard and was pleasantly surprised with the quality. The PCB has through hole plated holes on 0.1" grid, solder mask, smart buses for GND and key power supplies. The through hole plating makes it very easy to do point to point connections with a thin wire. We used the board for science project of my son to host accelerometer/compas sensor and few header connectors for connections to external motors and sensors.
