The warranty isn't as long as some of the other slats. The Lit link slat is only a single wall slat while other fence slats are a tubular shape making them a double wall slat. The lite link is still a very good slat. With a 10 year warranty you really can't go wrong. There is less material and they weigh less so there isn't as much material, thus the price should be lower.
If you don't think you will need privacy slats more than 10 years I would go with this one. However, if your chain link fence is 2 1/4 inch mesh I would get a slat made for that size. The lite link slat is only for 2 inch mesh. You can put it in larger mesh but the privacy won't be as good.
