[Q]: I'm unsure why this vendor is effectively charging 1/2 the price of many other sellers that don't even include the weather stripping. This is the exact same product, same manufacturer, packaging etc. It does a great job so I'm not going to question it too hard. A suggestion to anyone that wants to reinforce the sweep so not have to rely on the adhesive alone; use a small wood screw drilled through the upper part about an inch from the edge on both ends of the sweep. Space a couple more in the middle. PURELY OPTIONAL - Dip or brush screws with white paint BEFORE installing them (if you do it after it is really tough not to have any spots of over-paint and your white paint won't be a perfect match so it will show). Also make sure to use a flat headed wood screw instead of round head for cosmetic reasons as well.

[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!
