The product worked perfectly fine until it rained.  Just after a day of running around in rain and morning mist, the reverse camera had water inside it and it started working intermittently and was foggy.  But now the camera does not work at all.  This is after 6 months of use.

Absolutely loved the umbrella and was really excited to recieve it after reading through reviews on a ton of umbrellas.  Unfortunately, the umbrella stopped working after only 5 uses. UPDATE : the seller was kind enough to send through another umbrella no questions asked and this one works perfectly.  Has held up through an incredibly rainy (and windy) May!

it, of course, was left out a few times and it got wet from the sprinklers and it stopped working as smoothly.

Reading all of the reviews on this item, I thought I was going to get a product that would work well for my family.  I have a family of 7, so when traveling we don't have a whole lot of extra room in the car.  I got this to go on vacation and it worked great on the way to the beach, however, this item is NOT waterproof as it states.  We had great weather on the way there, so this held up well and is sturdy.  However, on our way home, we had a lot of rain due to a tropical storm that had moved in at the tail end of our vacation and when we arrived home, everything inside the bag was soaked.  We made sure to close the zipper all the way so that no water would get in, however, it still did.  I would not recommend this product if you are looking for something that is actually waterproof.

I give it 3 stars because it DID work as advertised... for one day. However, there is nothing in the literature that states this pump can't be left outside, but apparently it cannot. I left it up on my flat garage roof after it pumped off most of the standing water. When I went out to plug it in again a few days later after a rain... nothing. No power. Dead.  I thought being submersible meant it could handle the  rain, but apparently not.
UPDATE:
I'm back to revise my review because after the cord dried out, the pump started working again. I laid the cord along the top of a broom to keep it out of the water so hopefully it will continue to work.

Great product. But it breaks differently and slower in the rain.

At first I absolutely loved this product... then it rained... and now the lightbar has gone to sh**... water inside the light, light doesn't even work, tipped the light to the side and water just flowed out of it. Not even close to water resistant like it claimed.
*Update* contacted RACBOX and they have been extremely helpful with this issue. Apparently it is uncommon and they are sending a replacement light at no additional charge. Nice to have good customer service standing behind their products!

Was a great camera, until it rained. Fogged up and is useless.  Tried drying it out but what's the point?  Don't have any use for a camera that fogs up when it rains. NOT WATERPROOF.

**UPDATE** 1-27-16
After leaving a one star review the company contacted me and offered to send me a replacement camera. I received the camera in three days, not too shabby. Installed the new camera and it has been working flawlessly for about a month. I'm in Northern California and it has been raining for most of the month plus I`ve put it through 2 or 3 car washes. I guess the first one was just defective.

Customer service from this company was excellent. They could have made me jump through hoops and wait forever for a replacement or a refund but they stood by their product. They reached out to me, I didn't have to lift a finger! That's customer service! Five stars ...

The camera worked great for about 9 months. It survived rain, but then again my van is stored in our garage and I live in San Diego. For some reason this weekend the camera became waterlogged during a trip through the car wash. I am shocked it wasn't sealed better.

I bought this product and was very excited. It is a decent product at first but I took my bike out in a light rain for about 30 minutes and when I got home everything inside my bag (including a $100 Textbook) was soaked. I understand there is a difference between water resistant and water proof but this is not very water resistant at all. Be aware if you buy.

Rain destroyed it within two days of receiving it. It's just not sealed at all, and no conformal coating on the PCB. It worked well for the first day while it was sunny and the range was excellent.

This product was exactly what I wanted, but I might have to return it. We've had almost no rain since I bought it!

I initially gave this 5 stars because it was easy to install and was very bright.  I even ordered 2 more.  And then FIRST rain storm hits and now it no longer works.  Very disappointed.  It is suppose to be weather proof.  Not sure how else to protect it from the rain.  It is currently installed under the over hang in my backyard.  Where else could I POSSIBLY install it outside without getting wet???

I have been using this headlamp for a year or so, and after using it for the first time in the rain is stopped working all together. Thankfully Black Diamond has issued me a replacement with the note that "in the future know that if you don't take out the batteries after using it in the rain and let the unit dry out then it will become unusable. As a courtesy we will replace this headlamp for you this time, but going forward we will not replace a headlamp if it is not thoroughly dried out after getting wet." The item description stated that no maintenance was required after submersion but that does not seem to be the case. Just a heads up to anyone looking at purchasing this item.

The product works great until it rains. The straps that run through the car bring the water in and soaks the inside. My seats now have water stains on them

Has worked fine. It claims to be weatherproof, but that's not really true. I put it on my front door, where it is protected by a porch roof. On a windy, rainy night, enough rain blew onto the door so that rain soaked into the light, the batteries got "fried", and it ceased to work (even with new batteries).

Surprisingly, after being dried out for a few days, it is working again. But I don't think "weatherproof" means that rain that blows in (i.e. not direct exposure to rain) could potentially break it.

It has survived for almost 3 years at that location, so maybe it was just an unlucky night. But I will have to remember to take it down and bring it inside if I think it will be rainy AND windy.

I was tempted to give it only 3 stars because of this, but I paid $15, and if it ends up dying, let's say, every 5 years from a rain storm, that's not bad.

But others who live in rainier, windier areas might want to avoid it.

This product is comfortable to wear and easy to use. That being said, I only had mine a few months before I started having problems with it. The shine is described a waterproof, but once you open the compartment and switch out the battery, that is no longer the case. I got mine wet once (dunked in the lake) and the electronics went haywire. I tried drying it out, putting in a fresh battery, etc. No dice. The clock feature stopped working, and the unit would no longer accurately sinc with my phone app. Last time I tried to sinc it, the read out said that I had done 4 steps for the entire day. If you don't plan on using it for activities that would expose it to water, it would probably be fine. If you are looking for a waterproof gadget, not so much.
