"Changes quickly and is such a realistic red! I scared my boyfriend quite nicely! Thank you! The surface does feel papery, so it’s not one you should use regularly, but it’s good for a nice prank!"

"Exactly as described, it is amazing and horrifying and wonderful in the guest bathroom (where no warning is given)."

"This was ordered as a Christmas gift but we had to try it! The mat was packaged perfectly, arrived quickly and worked great! Highly recommend this!"

"My lady love has dreamt of owning one of these for years. She has been sucked into the misleading ads of the pre-printed versions that sound like they change, but are just printed bloody footprints. This is the real deal. Perfect white mat. Blood appears when you get water on it."

"I did not expect much from this, since it seemed hard to pull off well. This was one of the gifts I gave this holiday that stopped the room so everyone could check it out. Worked even better than imagined and hilarious reaction. I already bought 2 but I am going to end up buying more for myself. Love this product."

"This was such a fun gag gift, the package was so simple and the product itself is very unassuming when you look at it. However, we wanted to try it out (just to see what it did) and immediately after flicking water towards it it looked exactly like blood splatter. We did it at a Christmas party and you heard the whole room gasp in surprise, then start roaring with laughter!"
