Seems to work great
Product delivered didn't look anything like the picture but fit inside the old Spacegard shell with no problem. The filter is a rigid, freestanding unit shaped like a box fan that fits perfectly inside the existing Spacegard shell after the old filter and pleat combs are removed. Be sure to check your airflow direction arrows before buttoning up the system.  Very handy not having to sit down and fit each pleat spacer any more.  Seems to have good fit inside the duct without needing additional insulation like the original filters.  I didn't think $30 each was bad considering I was buying the original filters for $40 from an HVAC company and installing them myself.  The original filters also had a problem with spreading fine white dust throughout the house...see if the new filters have the same problem.
