I got the two in one Vacuum/Duster So after using this on all my keyboards and controllers I was actually surprised at the job it did.
It came precharged and I was able to clean all my items without it running out of battery.
It's fairly heavy for its size and even though it's plastic it feels very strong which makes me feel like it's a quality product.
The only downside I could find on this product was the flap on the collection canister that holds everything in, when not in use is very loose making it possible for dust and debris to fall out which is why I couldn't give it 5 stars. However this issue can be solved by emptying after every use.
Overall I'm happy with this item but if they could improve the loose flap on the canister it'd be just that much better. Definitely would recommend
