Rated 3.3 out of 5 by 4 reviewers.
Rated 4.0 out of 5.0 by Nice design at top, a bit longer than standard 4 foot posts It is pressure treated without that annoying green or brown color. We purchased these posts for several reasons: they are a bit longer than the standard 4 foot length, thus fitting perfectly into our project needs; The top has a more intricate design than most regular deck posts. We topped it off with a black cap (purchased elsewhere) to give it a finished look and to better match the LIGHTNING RAIL that we also purchased at Home Depot (see separate review on it); the price was right in line with redwood 4 foot posts; and perhaps best of all - the shipping was free and fairly quick. I only give it GOOD quality because there are some splits in the wood in some places. I don't think it will affect it long term, and it was not a deal breaker, but appearance wise, its not as 'pretty' as a sleek looking brand new piece of redwood. But, perhaps, for you, that splitting is the rustic look you want to have? It sealed really well with BEHR Waterproofing Wood Finish. August 12, 2014
Rated 2.0 out of 5.0 by Pressure Treated Posts Home Depot has been very good about working with me on the issues I had with these post. Great Customer Service!. Having said that---the quality of the post are poor. Almost every post had blemishes and cracks in them. In order to use these I spent nearly 20 mins hand sanding each post and bought wood filler to fix the larger imperfections. Out of the 30 post that I received maybe 6 or 7 were ok to use with just sanding. Also after installing them and attaching the rails you would have to cut compound angels to make them fit tightly due to the twists in the posts. This was very time consuming. I suppose it would make a big difference if you could hand select them yourself, not possible with an on line order. I wish I would have just bought good pressure treated lumber and capped them.
