Use at Your Own Risk!

Amazon's ad states that this stuff "works on most surfaces and glass" and that it "won't damage furniture." However, here's what the manufacturer's instructions that come in the box with the product state:

"We recommend the product for use on impenetrable objects and surfaces only. When we say 'impenetrable,' we mean a surface or object that is completely impervious to moisture or water. It must be completely waterproof. Objects considered completely waterproof are glass, crystal, porcelain, Formica, tile, polished granite, certain varnished wood, metal and many others. If you use the product on any other surface, you run the risk of staining which may not be removable."

On the next page there's this warning: "Be sure to read all written material and use this product at your own risk."

Given the possible negative consequences of using this goop to hold down glass objects on my tables, shelves, and the fireplace mantel, it's going back to Amazon or into the trash.

So at first I thought this product was great! My husband cut his finger on it trying to push the core out with a wooden spoon. I thought whatever he just didn't know what he was doing....until I cut my finger the exact same way in the exact same location! It's a total death trap! My finger bled for 2 whole days and was sore for 2 weeks!! I am not a baby but this cut was terrible!! Buyer beware! I would caution against this product!! You have been warned!!!

Make sure you order this product by itself, otherwise there is a high likelihood the comparably thin bag might get ripped (a happened to us). More importantly, after we spread this stuff around the corners of the rooms, my wife and I both got coughing attacks at night when we were trying to fall asleep. Not sure it is safe to be used around humans (despite its claims in the product description) - we ended up having to clean it all up, getting out the vacuum in the middle of the night to get rid of it. I would not recommend this product for use in bedrooms (which is the place where it would be needed most if you are trying to fight bed bugs).

Wow, pinch me is it really 2011 and we still have consumer electronics catching fire? Where is CE, UL, BS when you need them?

Fortuitously I was next to the amp when the wisps of smoke started, followed by a crackling fire. The amp as spec'ed is decent and worked fine - until it decided to self-combust. The real concern is that this is configured as an 'auto-on' device, so it switches itself on when it receives an audio signal on the line-in: this means it is often going to be put somewhere out of the way and unnoticed - and that makes it a REAL fire hazard (as in 'burning the house down' hazard).

So if i could give is a zero or negative star it would be duly awarded. Since now at least three reviews have indicated there is a real fire hazard, Amazon need to look carefully at what they are offering.

Received the 12-ounce bottle on Jan. 26th and have been using it for ~4 weeks now. I like the look of the bottle and that it is made of glass.  However, the manufacturer should attach a very big warning not to accidentally overfill the bottle and cap it! Earlier this morning when refilling my bottle, I had accidentally added a bit too much water where, upon screwing on the lid, some water leaked/got pushed out. I didn't think much of it and put the bottle in the refrigerator. Tonight I took the bottle out as I got ready to take some medicine.  As I tried to unscrew the cap, it would not budge and there seemed to be a strong suction keeping it down.  I saw water bubbles building up as though pressure was building up inside the bottle. Then, without warning, the bottle broke in my hand at the very bottom -- like the circular glass bottom just broke away and water came gushing out all over! It was like crazy water pressure that built up just from the bottle being overfilled! The whole bottle luckily didn't shatter (picture attached), but the bottom cracked off and the glass broke... just like that. I was speechless.

My son has been swimming since birth.  We have never used this brand before but gave them a try.  I followed directions putting these over the opening of his ears only as I always do.  Within minutes he came to me complaining water was getting in his ear.  Imagine my shock when as I went to remove the plugs and put in the old ones and found they were melted INSIDE HIS EARS...BOTH!!! We had to go to the ER (can't wait for that bill!)  The ENT MD said these should NEVER have been used for this purpose and can cause hearing loss, infection and all sorts of problems.  Way to soft and mealy... like a piece of gum.  They literally melted into pieces right into both his ear canals and the only way to retrieve them was by a doctor! I called Amazon to warn them about this item.  So scary!!! You've been warned!

I had read reviews that said that the cartridges sometimes arrived with some leakage into the bag, but the other positive reviews persuaded me to try them. The yellow and magenta did have a small amount of leakage. The large black one did not. I was careful when taking the cartridge out of the package and used paper towels to set it on, just in case it dripped. When I opened it and removed the orange tab, ink EXPLODED out of the cartridge. It ruined my scrubs and dripped onto a lap quilt made by my sister and mother.

The only way this company can possibly redeem themselves is to not only refund my purchase, but pay for a new set of scrubs. The damage to the quilt is irreplaceable.

DO NOT BUY THESE. But, if you decide to, please be very careful. Wear gloves when removing the cartridge from its packaging and wrap each cartridge in paper towels when removing the tab. Then, if it doesn't leak, pray that it doesn't ruin your printer. Thankfully, I didn't get that far.

Dangerous!!! I brought this with me on vacation to South America to convert 220 to 110. It heated up and started smoking and nearly lit the hotel on fire. I had a phone connected that got damaged and also another device that is now melted. Despite the decent reviews, I would advice caution with this device. It has cost me a lot of money and pain on vacation.

Very dangerous. Sure, not every one may be this way but mine was. It worked flawlessly for about 10 shots with my 70lb PSE compound bow. On the 11th shot I got the bow to 3/4 draw before the release let the arrow go on it's own. I figured I might have pressed the release button but I tried it a second time and the same thing happened. This is extremely dangerous, the first time the release let go my draw hand hit me in the face. Do not buy this, do not take the risk.

We purchased the first one, and used it for about a month. It began grinding and stopped producing any mist. Being optimistic, I requested a new one. The second one we used for several days, and it now shorts out and will leak water everywhere. Buy this item at your own risk!

I've had one of these in my massage room, and today during a massage it burst into flames!! The wax was getting low, but I figured that it would burn itself out like normal candles do. Not at all! Luckily I was in the room with my client when it happened. The entire metal container went up in flames, and I had to leave my client on the table and run to get water to put it out. The flames flared up about a foot into the air when I put the water on it!! My husband said certain metals when burning hot, like aluminum and titanium, will flare when water is added. Nice. Not exactly the kind of container you should burn something in, I'm thinking. It burnt a black circle into my wood end table, which is now ruined. The scent is definitely lovely, but I wouldn't purchase this again. I took pictures of the candle and the table and will write the company as well.

Made a terrible mess - would not stick to anything but my hands!

Take incredible strength to even get the product out of the tube.

Pretty impossible to use once you do get it out of the tube as it would not adhere to the surface.  But it sure didn't have any problems adhering to my hands!!

stay away!

Spontaneous discharge!

DANGER, DANGER, DANGER!

This product spontaneously discharged in my hiking backpack while being stored in my house.  The backpack was hanging on a hook with nothing pressing against it and the canister discharged its contents into my house.  The safety cap is still on the canister and has never been removed yet it discharged and ruined the holster, my favorite hiking bag, and left a red stain on my floor.  Oh, and it took a while to stop coughing up the pepper spray that was atomized in our house.

I'm disappointed with this product......

Update: the seller contacted me and sent a new canister of product and a new holster and seemed genuinely concerned about what happened and interested in discovering why the discharge occurred.

Even though I am very disappointed with the first one I received I would absolutely do business with this company again based on how well they handled the failure of the product.  I'm storing the new canister in my garage though, just to be safe!

Very Dangerous, couldn't even use for long, made my heart start beating really fast, almost like a heart attack, everytime I tried to use it, not worth the risk. I think it might also kill humans too. Would give it zero stars, if able too............Please don't buy this stuff

Don't use this product if have Porphyria.  It contains a solvent, and I've never gotten it out of my carpet.  The company laughed off my complaint - even though the product made me terribly sick!  When I asked for help in removing it from my carpet, I got very bad advice - as they said to use their All Purpose Cleaner to get it out.  They don't even follow their own MSDS (safety) sheets, and the 'combination' of these two chemicals was wicked!  I could have died as a result of this chemical exposure, and they could have cared less. So be careful of so-called 'non-toxic' cleaners.  What is safe for one is not necessarily so for another.

DANGER!! Do not bring this weapon into your home! This umbrella caused extreme injury and the manufacturer does not stand by their product! Be warned!! They even state that it is a dangerous product on their website. They assume that if you use their umbrella that you should know they have a tension spring that is strong enough to kill an animal. Broken bones, doctor bills, many weeks of therapy---this company is making 50 million dollars a year and they don't care about you!!!

The first time I used it, ball that links the clip to the screw on the camera, gone worn off and my camera fell off! Thank goodness I was standing over soft grass!!! If I was standing over cement, I may have broke a few thousand dollars of equipment! I modified the strap with a different Caribbean clip, but now it doesn't swivel the way it's suppose to. USE THIS PRODUCT AT YOUR OWN RISK!!!
