EUKI Compressed Air Duster

I purchased this product about a couple of weeks ago. My primary motivation was to use this to aid in drying hard-to-reach areas of my car (door hinges, window nooks, and crevices) after washing my vehicle and using it around the house for other purposes. While the device does deliver decent airflow to evacuate water from those hard-to-reach areas on my car and around the house, the battery performance has been a significant letdown. Despite indicating a full charge, the duster operates on its highest setting only for a couple of minutes before the battery depletes. This issue has now occurred twice. Both times, after ensuring the device is fully charged, it only lasted long enough for me to clean all 4 window sills, front door hinges, and around the emblems on my car. About 2-3 minutes of continuous operation on the highest speed setting. I brought it back in and put it on charge, and the device lights showed that it was already fully charged. Mind you, the weather is also cooler, so the device is not heating up to a point where it's shutting itself down. This makes it impossible to complete a full car detail (and I'm not talking about drying the entire car with it. This product does not have the air or volume flow to make that happen. Just hinges, window edges, etc). For light household tasks, such as cleaning keyboards or small electronics, it might suffice; however, for more demanding applications, the very limited battery life renders it ineffective. Given these shortcomings (maybe the fact that I've received an actual defective unit), I cannot recommend this product for anyone seeking a reliable tool for cleaning tasks.
