Good product but no documentation
Probably a lot of one-star reviews would not have been posted if the seller had provided the keypad pinout. With reference to the attached photo, the R and C (row and column) lines are:BLK - R2ORA - R3GRN - C3YEL - R4RED - C1BLU - R1WHT - C2I had no issues soldering the header. Fine tip is definitely recommended.

Doesn't take solder, DON'T BUY
Can't get it to solder properly. Pads don't take solder, cant test it if it doesn't take solder to wire it up.Even tried scratching pads and still didn't work.DONT BUY!

contact points easily pealed off
The connectors can easily be pealed off.. I hope they consider using plated through holes so they don't peal off by the soldering machine. or provide headers (facing the opposit side

The Tegg keypads are as advertised
The keypads arrived in a very short time, and in new condition. Decoding with a VOM showed that pins 1-3-5 were columns, pins 2-4-6-7 are rows. Resistance of keyswitches is several hundred ohms on the unit tested. All in all, no complaints so far.

Update to my previous review.
Initial ohmmeter readings showed that most of the keys read around 20 ohms when pressed. Some of the keys read several hundred ohms when pressed, which caused me to conclude that they were defective.However, when I connected it to my Arduino board, all of the keys did function as advertised. While there is no guarantee that this keypad will function correctly in your circuit with the high resistances on some of the keys, it did function correctly with my Arduino Uno board.

Came on time and will work as expected to design.

Impossible to solder!
Contacts on the board are very thin and don't bond with the solder under any conditions. While trying to get them to bond, ended up heating them up to the point they lifted off the PCB and the board was ruined. Really wish they made this double sided, or had headers pre soldered sticking out the back
