I ordered 2 devices. Assembly is easy, only thru-hole components. Both devices work fine. The Test LED is very convenient: you can flash a LED from your target chip. When you can flash the LED, you know that you have programmed your device and that the clock that you chose is correct. The documentation tells you exactly how to assemble the boards and where to pick up the ATTiny board definitions. Very happy with these shields!
I bought the DIY kit, and I have to say that I LOVE this.
Assuming you have an arduino, this is all you need to start programming ATTiny chips. At a very reasonable price you not only get a programmer with a ZIF socket, but also a SOP adapter for surface mounted attiny chips!
Also, the seller is really helpful and communicative. I highly recommend both this product, and the seller.
Two thumbs up :)
