    Exactly as expected! Don’t take this for granted, I got fake chips last time I ordered from someone else.

    I just can tell you that this is one of those sellers that I have to say Thank You. The items were programmed perfectly, the packaging is just great, perfect presentation and the microcontrollers worked just excellent. If you can make the shipping time faster that would be a Plus for your company.

    Shipped fast and I was able to replace a damaged processor on my Arduino UNO. I ordered a couple more as backups in case I mistreat another UNO.

    Shipping time is out of our control. If you select the economy option, which is regular mail, it can take quite a while with snail mail. Expedited parcel is always available, and even Xpresspost. For US customers, we always ship Express orders with UPS or Purolator (handled by UPS in the US), rather than with Canada Post and USPS.
