V-Guard VG500 Stabilizer for 2 Ton AC Working Range: 170V-270V (Grey)

Fantastic, value for money, picture perfect

Stablizer is working just fine and discount given was terrific , reason i am cutting one star is because when i unpacked the item one of the screws was missing and one had become loose resulting in stabilizer being split open and a huge crack emerged since i deal with lot of electrical products i knew it would have no bearing on the working of the product , so i just put a tape on the crack and installed it ... but i am guessing this would be a dealbreaker for lots of other customers.

For almost 10 year old non inverter window ac of 1.5 ton its a good stabiliser. It stabilised the voltage in my home from 237 volts to around 224 volts continuously. I received intact warranty seal on my stabiliser. It makes very low noise almost negligible. It doesnt get heated up. Cut offs are also working good. It looks good, size is only around 3.5 kg. Go for it, its aluminium wires inside but for copper wire stabilisers you have to give atleast 11,000 rupees and copper ones last 10 to 20 years while aluminium ones last 3 to 12 years depending on voltage supply ,etc. Its vguard so I think according to ither people reviews, it may last 5 to 10 years atleast.

The company claims an operating range of 170V to 270V on paper, but the reality is entirely different. This stabilizer consistently trips at 262V, falling well short of its advertised upper limit. This is a massive red flag, especially if you live in a locality with grid-tied rooftop solar setups. In my area, daytime grid voltage naturally idles around 250V and easily spikes to 285V when the neighborhood load is low. Even during peak afternoon hours with multiple ACs running in the area, the voltage hovers around 260V to 263V. Because this stabilizer cannot handle anything past 262V, it constantly cuts power, leaving the AC useless exactly when you need it most. Attempting to get this resolved or calibrated via customer care was a frustrating loop. The frontline support couldn't grasp the technical issue. When a service engineer finally visited, he tried to justify the premature tripping by claiming a "2.5% accuracy margin" on the 270V limit (which would technically mean a trip range of 263.25V to 276.75V). Even by his own flawed math, my unit tripping at 262V proves the product is simply underperforming and defective by design. The Bottom Line: If your house's baseline voltage is around 250V, this model only gives you a useless 10V regulation window before shutting down. Constant tripping doesn't protect your AC; it actively damages the compressor through short cycling. If you have a solar PV system at home or in your neighborhood, absolutely skip this and buy a stabilizer with a much higher upper-voltage tolerance.

The product was well packed and delivered in the right condition. I unpacked and installed the product on my own without any outside help. All you need is a drill machine and a tool kit. I went in for a product with a slightly higher rating. It is meant for a 2 ton AC but using it for a 1.5 ton. Will know about durability only after a usage for some months. As of now it is working and provides a cut off for 3 minutes once power is restored. In the area I am living the power fluctuation is minimum. What they need to improve is the plastic casing locking of the two halves. However, it is a feedback meant for the manufacturer.

Bought for 2T AC. Just 1 month passed. My electrician was also appreciating this product.

Good

It's not working after one year of purchase waste
