Overall Rating: *****
Pros:- Cheap, ideal for Microcontroled Projects
- The backside of this keypad has a strong adesive, protected with a special paper. Just remove the paper and apply on desired surface. Easy to apply and Professional finishing.
- The flat cable connection has an apropriate lenght.
- The keys appear be durable
- Nice look
- Smooth touch keys
- Low noise and low bounce
Cons:- The force necessary to press some keys is different compared to another ones. At least in mine one, this disrupted a little bit the use of the device.
- The difuse plastic of keypad does not allow backlight (not a big problem).
Other Thoughts:It was much more cheaper than the same product in my country. It solved my keyboard problem in a big project, The general functionality was perfect. No much more to say.
Bottomline:Buy it. Worths the money!
