Buyer beware

For 12mm and 16mm Antivandal RGB "Colorpixel" Buttons

Ordered May 11. Shipped May 23. No communication from seller. Still waiting for product to arrive (delivered with no tracking).

Good product, no communication

For 10DOF MPU9250+MS5637 sensor addon, Teensy 3.0-3.2

Cool product, good quality but shipping&communication not great.
Seller didn't communicate so I had to open Paypal-case (with Tindie as 3rd party) and then the product was shipped (almost 2 weeks after payment).
Couldn't find any documentation so it took some trial&error to find the correct I2C configuration.
I used Kris Winer's great example (https://github.com/kriswiner/MPU-9250/blob/master/MPU9250_MS5637_AHRS_t3.ino) to get started. Beware, you need to change all "Wire" to "Wire1" and I2C PINs to 'I2C_PINS_29_30' (SCL1&SDA1) and set the interrupt pin to 31.

Great Quality

For 12mm and 16mm Antivandal RGB "Colorpixel" Buttons

I looked all over to find a small RGB metal button that came in low quantities and in high quality. It works great for what I need it to do and it took a month for it to come in from the day I placed my order.
My review:

Pros:
-Great Size
-Nice vibrant colors
-smooth operation
Cons:
- It's common cathode and not common anode (harder to use with led controllers, so I have to convert it)
-PCB pads could be bigger or easier to solder too.

I would recommend it!

great multi-use button

For 12mm and 16mm Antivandal RGB "Colorpixel" Buttons

The button is well done, very professional & solidly built. Only thing is that the solder pads are small, so you'll want thin wires for connecting it. Reading the spec, it is easy to overlook, but worth noting: This switches ground & you need limiting resistors on each of the RGB (+) connections.
This is great to show status of something & allow one button to do multiple things based on colour, eg: Green = started, Red=stopped.

Shipped quickly and well packaged. Arrived quickly in the USA.

Worth it: Yes!

Nice and clean

For Teensy 3.2/4.0/LC slim micro SD card adapter

Works very well with Teensy3.2. I use it to read and write files to sd card with the SdFat library (https://github.com/greiman/SdFat).

Really fit the bill -- and the Teensy!

For Teensy 3.2/4.0/LC slim micro SD card adapter

I just finished soldering this little gem on my Teensy 3.2 and am delighted: it worked great with both the libraries I tried (standard SD library and SDfat library). It doesn't even seem necessary for me to rate Documentation or Communication, because (1) the image on the seller's page was adequate to show me how to connect it, and a quick google search on TEENSY SD CARD was all I needed to do to get up and running; (2) the unit arrived quickly from the Czech Republic with no need to contact the seller. So, perfect scores all around.
Plus, at $8 apiece, this is the best bargain I've ever seen!

Well built! Fits exactly on my Teensy 3.2! Will be buying mo

For Teensy 3.2/4.0/LC slim micro SD card adapter

This is a really nifty add-on for the Teensy. Well built, sturdy, Definitely in keeping with the extremely small size philosophy of those who work with Teensy-related products. I plan on buying more, when I get onto the next project.

I didn't want to rate the documentation, as none provided. There is a very nice discussion of this in Paul S's Teensy Wiki pages, which is all I needed.
