I just bought myself a psiclops and it really rocks. I am surprised no one has mentioned them before, I did a search without any hits. Here is how it works... Have you ever noticed that when you get new tires, or when you leave the tire store and the car drives so good, but after a while, making trips to the gas station filling your tires using cheap pressure gauges the tire pressures in your tires are not exactly the same from side to side. In effect your car then starts to slightly pull to the side with less air... The solution seems simple, make sure you have the exact same amount of air on both sides of your car. The pisclops does this for you by filling two tires, typically your rear or front tires at the same time, you get a perfectly balanced pressure on both sides. Made from real die-cast metal and not plastic too, there are three models, a 0#-15# "Pro15" for those drag racers, a 0#-60# called the "Extreme" and a 35# - 180# "XL180" that is for those high pressure things for trailers, spare tires etc... I went with the "Extreme" Since I am not a drag racer. I am honestly impressed... It lights up and everything. The only thing I will warn you, do not do what I did, and remove just the battery cover instead of taking the whole thing apart... I accidentally took apart the whole unit to try and put the batteries in it... If your interested check out their web site: http://www.tire-pressure-gauge.com/ I bought mine at http://www.vulcantire.com/psiclops_t...refad=EQUALAIR I got it in a week, and they had the cheapest shipping. And it was $10 less than the equal-air website... If your into racing, or you like to have a nice driving car, this is a must have... John

its not a new idea
ive gotten as far as pricing the parts to make my own, but never did it.
i would do a four wheel equalizer if it were me so i could be sure that they were all equal, or just leave two off and have different pressures.
if i made one myself, it would probably cost about what you paid, so good find.

I knew it was not new, Actually I have seen them before, matter of fact i have known of this model for about three years... When I first started looking into it they were about $79.00 or $99.00 and I could not stomach that... $40 was more reasonable...

What i found really cool is when you pressurize it the face lights up so you can read it at night...

What I think is this one is just... sexy... if that makes sense...

I've seen similar things on drag cars before. $40 seems resonable for a quality tire pressure gauge, i never use those stupid stick ones on my tires i always use an actual gauge it's so old though i might just put this on the Xmas list. LoL. thanks for the idea.
