Product review (4 stars): Good.  Saved some money.
Fits in tight spaces.  Make sure that your water heater will fit in it.  It's plastic so be careful not to damage it (like me, but I patch it with some silicone caulk).  Saved me a lot of money and it fit in the small space I had for the water heater.  Good purchase.  Four stars only because it's plastic and I would rather have metal in this size.
