Does what it says! Great tool!
Worked as described! Easy to use and cleaned my su roof drains. To be detailed I also used warm water with vinegar to disinfect as well. After an automated car wash I heard sloshing water around the sunroof prior to using this. Now no sounds after using the same automated car wash! Will keep for my wife’s car when her sunroof drains need cleaning. Thank you!

good solution
works just like it should and brush will be helpful for some fouling buildup that a simple weedeater string might miss. one caution - this product didn't actually solve my problem. in my case, the drain plug at the end of the drain was completely plugged after 13 years of operation. and these kinds drain cleaning tools will not address that problem. nothing wrong with this product.

Great tool!
I got this for my Expedition. Water was making its way into the interior of the car after heavy rainstorms and I knew that there was a clog somewhere causing the water to back up into the car. This tool is the best! I used it to clean the sunroof drain and the outer drain that runs next to my windshield. It solved the problem and I haven't had a clog or water in the interior of the car since! I definitely recommend getting this. It took about 10 minutes to clean out all the drains in the front of the car.

No complaints here!
Definitely got the job done! Some hot water first and then I was able to shove the wire all the way down and it cleared all the blockage that was causes my roof to leak. 100% recommend if you have a sunroof!

Ummm this is amazing
I really never write reviews on products because honestly I forget but for this one I’m honestly impressed by this product. I had bought a new to me Lexus GX460 and while I’ve had cars with sunroofs before, I’ve never had one where it leaked into my car and also frying the heating element and making the gel leak for the auto dimming in both of my side mirrors. I’ve never had a fancy car like this either. But after doing some research about my mirrors, I found it’s common for a clogged sunroof drain to do that to the mirrors and then made the connection with my floor mats being wet when I thought my daughters water bottle leaked or it was her shoes when it rained. Nope! So I did more research if this was something I could do on my own before spending money I really didn’t want to do. I saw YouTube videos about using a drill connected to weed wacker string but then products like this came up too which seemed way easier lol. Ordered it, arrived next day (thank you Amazon prime) used it in both sides of the drains yesterday because today it was supposed to rain (lots of rain this spring) Got into my car this morning to bring my daughter to school and so far no leaks and it’s been raining since last night. I’m gonna keep an eye on the area but honestly I think this little tool is a game changer. Easy to use, simple design and very effective. Rinsed it off after using. Saved me some money !!!

Works but caution!!
Worked great the first couple uses. On the 4th clean out the brush came off down inside the drain line. Now I have to disassemble the vehicle to get the brush head removed from the drain line.

Sunroof / Moonroof Drainlines
Surprise! Garbage BMW Engineering has created a guaranteed water leak into the interior of your very expensive car with no word or warning that this will occur nor how to maintain it. When my lease started in March of 2019 and came to an end during the beginning of the COVID pandemic; like many, working from home lead to no driving and very low mileage. When time came to trade in my BMW, it was pristine, just slightly over 7k in total mileage, and the “supply chain issues” offer crap car choices and arrogant dealers slapping retail pricing plus a huge premium on top of that. I elected to keep my car but knowing that ownership of BMW’s is insanely expensive due to poor reliability after owning a few in my life and vowing to lease, not own these wallet draining machines. The sunroof started leaking very early on, during the warranty period when I kept asking the service manager to replace the poorly installed sunroof / moonroof rubber seal as it had 1” gaps and non-continuous rubber seal. Instead he installs gap fillers and explains this is adequate. At the time I was in lease mode and didn’t care about long term issues so I took him at his word. Through the 3-year lease period, I had to get this fixed again because the pieces of rubber shrank and gaps appeared again. Then came the end of lease and the beginning of the pandemic. After washing the car and in my corner of my eye I catch a drop of water coming from the ceiling above the driver side visor and landing on the floor mat where it would appear that the source would be coming from the heal of a wet shoe. The head liner was soaked at the driver side only. I took it into the dealer and was force fed the car was out of warranty. I reminded him of all the times I requested repair / replacement of the sunroof / moonroof rubber seal but only got poor service. This resulted in debris clogging the drain lines. He attempted to pass this off to me but that wasn’t going to happen. So after several poor attempts to clear the drain lines, they had to scope these lines and found that the routing was the problem and they had to dismantle the headliner and sunroof/moonroof to clear the driver side drain. That was successful but then the passenger side started leaking a week later. Took the car back in and after several weeks i got my car back with no leaks. One week later i had water intrusion to the driver side headlight assembly. i was quoted a $10k replacement cost which i was again reminded that my cars warranty had expired. Fortunately I had a great Service Manager that presented this to BMW where they determined this was on them and i got this repair covered. They tried to worm their way out of this by suggesting the car must have been in an accident, which it never has been. Bottom line, the drain line routing is suspect at best and you must maintain it as the slightest debris will cause water intrusion into your vehicle’s interior causing many problems. This drain reemer may not work all the time and it’s left to you to figure it out. Be patient and DO NOT force anything into the drain lines as you may cause more damage and problems for your car. If you’re in warranty take to the dealer and then request full disclosure on the work performed and how, if any, way you can maintain proper operation of these drain lines. Hope this ‘novel’ helps.

False advertising - it's not 120 inches, it's about 6 feet (72 inches) long.
