Review: Reliable - I have purchased this item on 19 th Aug 2020 and after delivering product I have called the owner (customer care) about installation and working. I remembered, owner said to me this will long last without trouble. I am writing this review in 2026. Really a solid product.
Review: Good product, Speaker can be improved and Light can be added - In our society we have purchased more than 15 Water flow Alarm. It works really great with good Sound. However after roughly after 1.5 years speakers stop working in several pieces since it did not have any Status light for Tank Full it is very difficult to know speaker stopped working unless tanks get overflowed. I request Manufacturer to Add a status Green Light as well and improve Speaker quality. Since we had some pieces where only speaker was not working and rest circuit was working I added a Status Green Led myself also I updated the speaker as shown in the video. Do note I am an electronics enthusiast guy so I opened it myself but I do not suggest anyone to open it.

### ⭐⭐⭐⭐⭐ Looks strong.Fixed today.Lets see if this one works for an year.
*by S***H on 6 July 2019*

Another update on update : Ist October 2025 update- Still working without an issue . Had fixed another one in my showroom and even that is working trouble free for more than 5 years Latest update - 7 Oct 2024 it's still working flawless, wow thanks to whoseover manufactured this , I am raising the stars from four to five now. Although I reduced one star for an absent plug earlier but I don't mind it now as the product is so durable, perhaps that's why he gave the basic thing , The water alarm as perfect by removing plug to ensure quality of remaining mechanism Latest Update 5th Nov 2023 after several years probably 4 years - Still works troublefree. Strange! on Oct 10th after 3 months,working fine . Original review as ist rcvd -Just received and fixed .One thing worth noting is that even after spending 490 rs , you won't get an electrical plug along with it as visible in picture that the unit arrived with naked wire connections .I have bought because the normal Chinese alarms ,where in a lady voice is there failed thrice within 3 months maximum for each alarm so I wanted a durable one and as claimed if this one lasts for an year or more I will call it the best buy .So fixed the alarm and keeping fingers crossed .It looks small but durable as body is heavy and seems of metal .Only thing that's bothering is an input electrical supply plug which would not have costed the supplier not more than 10 RS if he send along.Will update when it fails or if lasts for 3 months and 6 months and an year . Update on 5th Nov 2023 - never gave a problem. Still going fine. I feel blessed having spent money wisely. Though during buying I literally thought I wasted money when their are Chinese products available for 1/3 rd the price I spent on this one . I am surprised after seeing today that my review helped so many people and i had promised an update? So here i fullfilled it by chance when I accidentally revisited my reviews.
