Questions about this item

How long will the 32GB microSDHC card last before I need to replace it?

The card has no moving parts and is rated waterproof, shockproof, temperature-proof and X-ray proof, so it typically lasts for years of normal use.

What speed limit will I hit first when recording Full HD video continuously?

Sustained write speed is capped at 20 MB/s by the U1 rating, which is the bottleneck for long recordings.

Does the card get hot or draw much power during all-day dash-cam use?

It runs cool and draws very little power; the spec lists no thermal or power concerns for continuous operation.
