4PCS Transparent Silicone Thermoform Moldable Dental Mouth Guard, Whitening Teeth Trays Whitener Mouth Guard Care Oral Hygiene Bleaching Tooth Tool

This is the biggest rip-off of ALL rip-offs. For starters there were no directions but I remembered something about hot water. 1st attempt was a total fail and it was a glob of goop that stuck to my finger so I tossed it. The 2nd attemp is pictured, another glob that I didn't get to the sink fast enough. The 3rd was better but did not form to my teeth. After a short prayer I attempted the 4th one. Horrible fit and it made me gag. I will be reporting this to Amazon. No one should be losing money because of this rip-off.

Great fit great easy to use

This product does not work at all. The way it looks in the photo is as though the silicone will mold to all your teeth and all the curvatures your teeth may have. The reality is that it only captures the surface grooves of your back molars and none of the front teeth - and that's IF you can even get the mold to soften to the perfect point where the silicone doesn't completely stick to itself but softens enough to mold at all. Out of the 4 that came, 2 had to be immediately tossed cause they were so soft they kept folding in and becoming a sticky, crumbled blob and became useless.The package also came in a small yellow envelope that simply says Made in China - no branding, no instructions, nothing. I had to come back to this product page and follow the nonsensical instructions here for a product that doesn't even work. I recommend skipping this product as it's honestly a real waste of money.

It was ok. Not as good as I thought but they worked.

A little backstory, I got this because I lost my Invisalign and needed a temporary replacement until I got home in a few days. The picture of how perfectly it was molded to the teeth is what got me. I tried my best to follow the instructions EXACTLY the way they were written. There were 2 sets (4 pieces). and both sets failed to mold my teeth the way it shows on the pictures. It didn't even reach the back of my teeth

It help me

I looked up standard procedures to mold the forms which is basically just adding boiling water to a bowl and inserting the forms for 20-30 seconds and then dipping them in cold water for 2-3 seconds. Well, I had two of the pieces in a bowl, added the hot water and within seconds they stuck together and became impossible to separate damaging the product. The second time I tried the pieces separately. This time they became so soft that it was impossible to get them to fit over your team and create a "form". Basically, a waste of time and money

I had the same problem with it not molding AT ALL. THEN I reread the instructions and realized it asked for water in 80-90 degrees CELCIUS NOT FARENHEIT. this translates to 194 degrees F! I boiled water, took it off the stove, put the tray in the 194 F water for 15 seconds and it molded just fine. You just need hotter water,
