[Q]: This wig started out beautifully. Then it started shedding three days later. After shampooing and conditioning according to the instructions it became a stiff mess .The curls were no longer bouncy. It is dull, stiff and lifeless. I have lace front wigs I paid less money for that are still beautiful after 6 months and several shampoos. I am so disappointed with this purchase! I will never purchase another wig from Amazon!
[A]: negative


[Q]: I thought the impeller was broken so I purchased a new one and unfortunately learned that it is the filter itself that is no longer able to pump water. I bought this a month ago. My turtles are not happy.
[A]: negative


[Q]: 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.
