[EX Q]: This cable was fine for about 2 years using the cable with my genuine Apple wall charger. After that my iPhone 6s would start discharging while connected! Then it started to quickly cycle between charge - not charge - charge - discharge. If I look closely I can see dark spots on the gold plates or tabs. (See picture.) I will stick to reliable UL certified vendors like Apple or Belkin or Griffin. Because now my iPhone won't hold a proper charge.... Luckily it has not blown up or burned as in other reviews. The newer model seems to have been updated to avoid the weak flex point near the lightning head, but I don't see any more coating for the connection tabs.
[EX A]: Connection plates wear out and cause charge cycling

[EX Q]: The nut that accepts the threaded bolt (which connects the bike carrier to the hitch rack) is welded and the welding is defective. One trip is all it took for the nut to come loose and so, it is broken. Cannot tighten the bolt anymore. Luckily the pin stayed, otherwise it could have caused a major accident because the bike carrier could have come loose with the bikes and hit any cars behind us. So, watch out. This is not acceptable at all. Now, I have to manually saw the bolt out and somehow remove the rack to return. What a pain!
[EX A]: Beware, Weak welding of the nut in the tube that connects to hitch rack

[EX Q]: The lid just won't lock like it is supposed to, and because of this it leaks easily. My kids don't like it and I won't be ordering more.
[EX A]:
Does not lock easily, not ideal if you need a bottle that won't leak.
