Perfect Fit
Since parts are small, a little difficult to screw in the supports but, very stable once installed. The terminals worked perfectly and the pins fit snugly without tightening too much. Well labeled. I recommend securing wires before connecting to the Mega board if you’re just transferring. I Highly Recommend.

Best terminal block for Arduino Mega!!
The best thing ever! Originally used a different connector which sits on top but unable to remove an individual wire. This lets me have access to each wire individually.

Quality product. Great fit. Small profile.
Installs nicely. Wires connect at edges so important LEDs on board are not blocked. A good jewelers screwdriver is easier to use than the provided screwdriver. The nylon standoffs are fairly delicate so a light touch is needed. Extra standoffs are provided in case of problems.

Teenie tiny nuts
Good product, fits up well with the mega but the nuts are nearly impossible to fasten on. It would be cool if there was a tool to help with fastening them to the bolts.

Great for prototyping!
Well made, good form factor, a real timesaver. Easily install, relocate wiring as required. A bit pricey, but anymore what isn't.

No assembly documentation, solder flux not removed, bowing of pc strips, terrible standoffs.
Usable but sloppy workmanship. I bought two sets. Some minor bowing evident in one set and more serious bowing of one of the longer pc/terminal strip boards in the other. Connections appear to be okay but it is not ideal especially at the high price they are charging for the kit. Nylon standoffs are terrible! It is best to assemble the longer standoffs loosely to the strips before pushing the strips into the headers on the controller card because threading the tiny nylon nuts onto the standoff is nothing short of a nightmare. Fortunately, they include some extra standoff pieces which you may need if you are not really careful with this nylon trash. Assembly documentation not strictly required but at the price they are charging a simple picture of the finished assembly would be nice.
