- slow (low airflow) since it's a top-off inflator
- air hose is extremely short so the inflator is dangling & rattling against your rims most of the time depending on wheel/valve stem orientation
- screw-on chuck is annoying to use as someone else pointed out
- built-in pressure gauge is inaccurate so always verify with a separate gauge
Note: I don't see a need to get something better atm so I'll probably keep using this until it breaks (will also carry a high-volume bicycle pump as a backup, lol).
