1. It did not come with the customary thing tube That is used to spray it into tight spaces.
2. It had leaks all around the area where the spray is supposed to come out. As Soon As I sprayed, it ended up spraying everywhere, Including on my eye, Which really burned.
3. After a long bath and lots of eye-wash, I ended up getting some of it into the switches. Then I slid the switch back and forth. repeated 6-7 times. No effect whatsoever. Goo what not dislodged, and the mechanism is just as sticky as before.
If this stuff had not been so caustic getting it in the eye, and if it did not smell like satan's fart, I would have guessed it's just water!
in conclusion:
Bad spray, bad design, not effective.
