Not for the mass and not the historical lowest but best price I can find now. Ideal for those with prosumer full frames/APSC/MFT doing burst photography at highest resolution, or high frame rates 4K videos therefore needing fast Write speed.

Built for and tested in harsh conditions(3): Temperature-proof, waterproof, shock-proof, and x-ray-proof
I may have just had a faulty one, but my overwrite tab worked its way loose so every time I put it in the camera, it would push the tab into 'no overwrite' mode. Sandisk were pretty good about a replacement, but it took a long time to get back to me (sent November, received early Feb).
The burst mode is great, I do a lot of action / sports photography, so I find it very handy. During my time using a replacement card, the slower write speed and low buffer in my camera was very noticeable, even for things like focus stacking macro shots.
