PROVEN Isi Mark Eleven Zingo Alkaline + Orp With Copper + Ro + Uv + Uf + Tds Controller/Adjuster Ro Water Purifier-12 Liter Storage Home And Office (Made In India)

good purifier with added features. One can go for it on regular basis.The cost is veriable .When i had purchased it was higher but as on today it was lower.If u want to purchase from Amazon dont purchase during sale hours.Its cost is cosmatics. I had suffered same. Comany dont take any ownwership of costing , i dont know why it is their product ,there may be marginal diffrence but acctual diffrence is high. i had gone for white color purifier . Service all you can take from other venders.In pune local vendor of the company was not supportive.any how looking to present cost it is good product.Review is based on actual 35 days of actual usages ,service and other thing has to be seen during coming times.

the worst water filter ... after the installation it worked , from other day the taste of the water completely changed to a chemical water , after calling customer service , they told it would beta resolved , but after contacting many times no response from them , then after few days one engineer visited he told he adjusted some tds thing and BUT IT DIDN'T work same chemical taste water was coming from the filter , but the company is not listening to the complaints , as there is no indication of machine is on or is it off .my recommendations not to buy this product , as is waste of money ,

Good

Its good looking and everything working fine.. outlet tap giving less water.. we are 6 in a family.. its okay for that.. quality is good.. motor sound is little more.. overall its good for home and office use.

Ro is working very good

The media could not be loaded. We had a very good support and kind interactions with the technician. He installed neatly and quickly. Thank you.

The media could not be loaded. I purchased the Proven RO system a few days ago, and unfortunately, my experience has been quite disappointing. Here are the major issues I've encountered:1. **Poor Build Quality**: The materials used feel cheap and flimsy. Within the first month, a crucial plastic component broke, rendering the system non-functional until I could get a replacement part.2. **Slow Filtration Rate**: The system filters water extremely slowly. It takes hours to produce a few gallons of clean water, which is highly inconvenient for a household.3. **Frequent Leaks**: Despite following the installation instructions meticulously, the system has developed multiple leaks. I've had to constantly check and tighten connections, but the problem persists.4. **High Maintenance**: The filters need to be replaced far more frequently than advertised. This not only adds to the ongoing cost but also is a hassle to deal with.5. **Noisy Operation**: The unit makes a loud humming noise when in use, which is quite disruptive. I expected a quieter operation for a system that is supposed to be used continuously.6. **Ineffective Customer Service**: When I reached out for support regarding the broken part and leaks, the customer service was unhelpful and slow to respond. It took weeks to get a replacement part, and they provided little guidance on how to address the leakage issues.Overall, I regret purchasing the Proven RO system. It has been more trouble than it's worth, and I cannot recommend it to others. Save yourself the frustration and look for a more reliable and well-built RO system.---

Mr. Arun Mondal, product technician was very excellent.
