Rated 5.0 out of 5.0 by NJChris Worth the money
I purchased this item about 3 years ago when I made the initial purchase of my BWD system. It has sat on the shelf collecting dust until recently when I needed to add some distilled water to the BWD battery. I remember doing this in the past before maintenance free car batteries and always hated it. Well, this little gem of an item made the process easier and fool proof. Fill it with water, press it against the hole for the cell, and let it fill until it stops. That's the whole process. Repeat five more times and you are done. No more guessing on whether or not you have put enough water in, it fills it to the correct level every time. I will be honest though, I don't think I paid nearly this much when I bought it 3 years ago, but I would definitely buy again.

Rated 5.0 out of 5.0 by Allen If you have a Watchdog battery, this is a must have
Don't procrastinate on buying this item. When the battery needs to be topped off in the middle of the night, you don't want to fiddle with funnels and possible mess, not to mention the tricks with lighting you have to do to try to get each cell at the same fluid level. This makes it idiot proof and simple. It should honestly just come with their batteries in the packaging.

Rated 5.0 out of 5.0 by Danthehomeowner Simple watch dog refill bottle
I finally had the opportunity to use the prescribed watch dog battery water bottle. No mess no fuss. Previously this was a chore necessary but not fondly looked forard to. I would use a flash light to shine on the opposite side of the battery to show how much water was in each cell and then I would typically spill water attempting to fill the cells with distilled water. What a pain. This bottle makes the whole process of assuring the proper water level is attained and in a very timely manner.

Rated 1.0 out of 5.0 by TomK Can still overfill battery
I bought the filler bottle so I wouldn't have to worry about overfilling the battery cells and so all the cell levels would be correct and the same. The bottle does not provide a tight seal around the battery fill hole therefore you can still overfill the battery. It seems like it should have a soft rubber washer to provide a good seal instead of hard plastic.

Rated 5.0 out of 5.0 by PaPaDan This is just an outstanding product.
This product fills each battery cell exactly, without worry
you may over or under fill each one. It is so easy and quick
to operate and no more messy wet battery tops.
It was simple to order on-line and pick-up at the store two
working days later - that is quick and professional service

Worked as advertised but the filler nozzle broke after the first use and I can't find anyplace that just sells that part.

Rated 5.0 out of 5.0 by happiness442 Just used it . Worked great. lightweight and easy to use
Had bought a Watchdog battery, had markings on the outside to show fill to line. But to see the lines we had to lift the battery out of the case, very heavy . Knew there had to be a better way, store did not know of any. Found this on the"net". There was no mess,fast and easy. Don't know what other people do but this is the way to go. Surprised stores don't carry them
