This cost me forty bucks here in 2021. That's not nothing but then again, compared to the cost of a fancy pants Sigma Lens, it's insignificant. Simple enough to use, I was able to both update the firmware for my big lens and reset the lens to factory specs. Looks like it should last forever. Great deal. The Sigma website though can use a little work. To use the device you have to download the program from the Sigma website. Nice, good looking website. Unfortunately, when you get to the screen where you have to agree to the terms of service, you know the one, click on I agree and you're on your way, there's no apparent way to get to the bottom of the screen to click the silly I Agree deal. Try the up arrow, the down arrow, the index on the right for up or down, hit enter, nothing works. No instructions on how to do it either. Hit the space bar. It goes where you want. Then you can use the device. The device is great. The website, not so much.Read full review
