This is the first bad product I've ever gotten from Monoprice. Works for a couple weeks then won't stay connected and charge. However, customer service followed through with their promise and replaced/refunded the 4 cables that failed. It's a risk if you buy them but it's a great price and if it breaks, MP will stand behind their warranty.
Perfect at first but stopped fast-charging after several weeks
I like these cables I've purchased several of the 3 foot and 6 foot versions. The USB-C cables have stood up a bit better than some micro-USB cables I purchased from MP around the same time. Initially the USB-C worked well for quick-charge of my Nexus 5X. However, after several weeks the Nexus began to refuse to quick-charge with these cables (quick charge still works with the original Nexus cable). I'm still able to charge at normal pace so I give it 3 stars for that. Disappointing that the cables don't seem to survive quick-charge use as many other reviewers have noted.
PROS: Good build quality.
CONS: Capability appears to be below minimum requirements to survive use as a quick-charge cable..
