I have been using one for about 9 months now...they are much lighter (obviously) than steel tanks, making the install easier. The quality seems good, the plastic was thick and the manufacturer claims it is as strong as steel. One thing I do not like about mine is the filler neck diameter is only an inch, which makes filling the tank rather tedious. I ordered a send unit from a different website than the tank. My tank did not incorporate the lock ring on the sending unit that is used on the steel tanks, it came with screw downs that seem to work well.
