Replaced an older cover with this one.  This one has been great.  I had to use a couple of wooden platform/poles I made to hold cover up to avoid water pooling, but even when the poles failed, and many gallons of water pooled in the cover, it did not tear.  Great, light colored material looks good and does not stick out.  Moisture and/or condensation does not build up under the cover, so there are no nasty surprises when I remove cover.
