Pros: Ability to set target pressure

Cons: Loses pressure instead of adding pressure

Overall Review: It lost air pressure when I connected it to a tire... I bought two of these, and was looking forward to the ability to set a target pressure and leave it. But the first tire I tried it on, I set the pressure, walked away, only to come back and find that it was now at a lower pressure than I started with. Total garbage! EDIT: Raised the review status, as the seller saw the original review and offered to replace the faulty units. I had already disposed of them, and did not want them replaced, so they offered to refund my money, no strings attached. So while I did not like the product, their customer service went above and beyond!

Pros: One drive worked fine right out of the box...

Cons: ... but the other drive kept "dieing" (i.e. no drive access, and drive no longer showed in explorer or disk manager) less than an hour after connecting it. A reboot would temporarily restore it, only to have it die again shortly thereafter. Already requested an RMA from Newegg.

Overall Review: Can't beat the BF price, but wish it would have been a higher quality drive.
