Ex Input:
I'm very disappointed with this purchase. 2 of 3 pack doesn't work. First cable does not charge at all with an error message saying "This accessory may not be supported" within a few seconds. The second charger appears to be charging but then just randomly stops charging.

Ex Output:
negative

Ex Input:
First off they don't give enough washers to assemble properly. It's difficult to assemble. Once assembled the feeder bar plugs very easily with fertilizer even with dry fertilizer but has slightly soft pellets. The material I was using has a black pellet that plugged the feeder bar. The 3 bags gone. $150 bucks. Most fertilizers now have soft pellets. This thing plugs them in the feeder bar and it turns into a solid bar. It needs a different feeder bar to work with today's fertilizers.

Ex Output:
negative

Ex Input:
It was easy to use yes. But it didn't hardly give any color. The color I had was very spotty! It took using over half of the bottle to even start to notice anything.

Ex Output:
negative
