Product review (1 stars): Failed after only three years of light use.
The cold water hose (I don't use hot water) corroded at the wall connection and is leaking very slightly. I only noticed it because I was changing out the dryer. Left to its own devices it would get much worse.

The elbow was also leaking after removing the hose and reinstalling it (as a stopgap measure), so I'm glad I caught this before it was too late.

Do not buy these hoses, go with brass or single metal hoses.
