Zank brother i have this Universal Stabilizer lying under my bed in 100% working condition, it was used for hardly a month or so (as Voltage issue was resolved in my area just after i bought this unit!), worked EXCELLENT with Pel 1.5 ton Window type AC, now its sitting idle for 6 - 7 years.
For its Working or any other Flaw i can give full 1 week return warranty, this unit was bought from an authorized dealer of only Universal Stabilizerss and is a lot heavier than today's Universal (Y)
Never opened or Repaired is my Guarantee ! if you still havent bought a Stabilizer then i ll give you this one for a good price (Y)
