Best product for sure
I left my car for like 45 days and travelled abroad, due to some water leak, it spilled on car boot and it was full bad condition. I went to polishing shop but no use. They suggested to paint as this is unremovable, I searched google and got this product, it worked like charm. As the damage was bit high, it took some time with extra power. But it worked. I highly recommend this product as it removed 100% for sure. Use micro fiber which makes it easy as well.

It's ok
It's ok at what it does, but I wonder if it's worth the money? You still need to apply a fair bit of effort to remove any water stains and I don't know if it's more effective than any other spot remover/detailer that you could use for small areas. Anyway, I've given it a try and it does work, just not sure that I'll buy it again.

Did Absolutely Nothing – Extremely Disappointed
I bought this product specifically to remove water spots from my car's windshield and windows, and it was a complete failure. I followed the instructions carefully, tried multiple applications, and even used extra elbow grease — nothing. The water spots didn’t fade even a little bit.Not only did it not work, but it also left behind streaks and a hazy film that made the glass look even worse. The smell was strong and unpleasant, and the overall experience was just frustrating. For something advertised as a water spot remover, it did the exact opposite.Total waste of money and time. I’ve had better results using homemade vinegar solutions. Don’t bother with this — it’s all hype and no results.
