Great product!
Much easier to use when prototyping. All connection screws are accessible without removing an entire row of connections. This was designed by someone who has suffered that pain! Good job!

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 youโre 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.
