    Works as described. I found it easy to use and to be very accurate. I guess I was lucky to get an accurate one as some found accuracy to be a problem. For a low cost meter, the specs of within one tenth of a gallon accuracy is not bad — mine is actually much better than that. I tested accuracy by measuring in a three gallon bucket — 3 gallons in the bucket read EXACTLY 3 gallons on the meter. Time will tell how well it holds up under use. I have ran over four hundred gallons through it and it is fine.

    Fantastic buy! I bought this for use with my travel trailer fresh water. I don’t like to travel with more water than I need due to the weight. I used to have someone in the trailer checking the level reading and stop me when it was flashing at 1/3. The accuracy was questionable at best. Now I can add exactly the quantity I need without having a second person or running inside the trailer to check the level. This is a must have if you have a travel trailer.

    I use this to fill our camper fresh water when we start a trip. I allows me to fill the tank to full without overfilling. I also use it to calibrate our tank sensors, You know exactly how much fluid is in the tank. Very economical and works great. Haven’t had to change a battery yet (couple of months use now), it auto shuts off when not being used.

    I use this meter to monitor my water usage in my RV. My holding tanks are rather small (30.5 grey and 22.5 black), so my usage is important to know when to dump my tanks. This little meter is really easy to use and will track current usage (top number) and total usage (bottom number). The top number resets under two circumstances: the device goes into sleep mode a couple minutes after water flow has stopped or the left button is pressed. The bottom number records total usage and does not reset when the device goes into sleep mode. It will reset if you push the right button for 3 seconds or so.One thing to note is this meter is very small. I assume the battery is user replaceable, but it is not a standard battery (like AA or AAA). I cannot attest to how accurate this meter is, other then I went camping and used 33.5 gallons of water (mostly grey from shower and sink) and I did not overflow my tank. This makes me feel that this meter is close to accurate, or does not under report water usage. I highly recommend this product.

    Made this purchase so I could fill our fresh water tank and know how much we are filling. Works as advertised. I’ve only used this a couple of times but it’s worked great for what we want to use it for. I was concerned with the plastic hose fittings might take some wear being continually installed and removed but at this point it doesn’t appear to be a problem. Great product. Very happy with the purchase.

    I bought this so I could monitor how much water I was giving each plant in my greenhouse. This little unit has been sitting outside in the sun for 1 and a half months now. It has been rained on at least 3 times. I have been trying to keep the lcd screen facing down (in a bed of straw) so it doesnt get damaged by the sun. Other than the spinning little turbine inside getting clogged with pine needles a few times I have had no problems whatsoever. I water from a water barrel with a pump. I have this unit attached between my hose and water wand. The only complaints I have are: if you are watering with a water wand, the readout is upside down, and it is too easy to accidentally bump one of the little yellow buttons and restart your count. So no DOA for me and this little unit seems pretty robust, especially for the price. It also seems pretty accurate. 5 gallon bucket read 5 gallons. I have had none of the problems that people have complained of in other reviews. Love it.

    I bought 2, great for mixing salt brine at correct ration when the mixing tank is never emptied, and you want to know how much water has been added to calculate salt to add. I also use one on my my sprinkler irrigation system to know how much liquid fertilize to send down the line. I just run each chancel ( 8 of them) until the gallons read say 8.4 gallons, and I shut down the fertilizer injector. As each line is a different length, I may need a different feed gallons for different lines. works for me. saves lots of water. and lets me know how much water total I have used this year.

    Despite other reviews I have purchased a few of these meters over a 3 or 4 Year period. I have never had any issues with the product that wasn’t caused by me, such as dropping it on a concrete floor or after a while they get gummed up with nutrient residue after 6 months of use. I use them to water my indoor cannabis grow I find them to be fairly accurate and dependable. Will keep buying them as needed.

    I use this meter to back flush the tanks in my RV. The tanks hold 40 gallons each, so I have to be careful not to overfill them, but still get as much water in them as I can. The meter registers in tenths of a gallon and I have no issues with overfilling the tanks. The meter has two lines of display, and can be reset individually. This allows for one to be used to measure total gallons, and the other to be reset for each tank. I haven’t had the meter for long, so I can’t say how durable it is or how long the battery lasts. It does shut the display off after being disconnected from the water supply. The battery is a common button style like watches take.
