These suppressors work great. We had a lighting surge and in the past it has taken out our alarm autodailers. We installed the Isobar4ultra on our new autodailer. We had another surge in the power and the component that protects the phone line in the suppressor completely fried. It didn't hurt the autodailer at all. The best part is when I called Tripp-Lite to see about getting it fixed, they just replaced it for free. Talk about value. I protect all our autodailers with them. It is money well spent.
Had one die from a lightning strike. (Their tech confirmed) Immediately received a replacement unit. I also was able to claim the insurance (replacement cost covered) for the damaged equipment.
Was having interference from treadmill to the TV. Purchased the ISOBAR4ULTRA for the treadmill and this took out all the interference. We can now use the treadmill and TV at the same time. Five other people tried this and the ISOBAR took care of their problems. You have a lot of happy customers.
Great dependable surge suppression. Use in office, industrial, or any environment with electronic equipment. Tripp Lite backs their hardware and will replace without question if mechanical or electrical failure occurs. I have had these units sacrifice themselves protecting equipment from lightning strike surges - Tripp Lite replaced quickly. Highly recommended product line.
