As long as you are trying to screw people over by raising the price on these I will never buy them.  I can buy my grandson 20 Hot Wheels cars for the price of one pack that will only make five cars!  Wise up and put the price where it should be!

Bought two in preparation for the opening game only to discover on packaging in Fine Print that these will not work in cars with side airbags. Needs to be a Warning on site!

Should specify that this cannot be used with 4wd models. These shorty headers only work where there's no pesky front axle in the way.

I first purchased two of these cars as gifts for 7 an 8 year old boys.  Within the first two hours of the boys using these cars - one of the cars stopped working and the other had a broken on/off switch - but still worked.

I returned the car that stopped working for a new one.  Right out of the box - the replacement car didn't work AT ALL!

I checked the batteries and opened the car up to look for loose wires, etc - but couldn't find anything.

MY FINAL OPINION:  The company that makes Morphibians has major issues with using cheap quality electronic components and apparently, there is little quality control for what goes out the door.  Its too bad because the actual body and wheels of the car is made of fairly, sturdy and good quality plastic - unlike many other RC cars.

Worked on most of the items but my car connection.

It only works if you have a drag car no street car so keep that in mind before you purchase

These are listed as being compatible with cars that have bulb sensors but on my VW Phaeton they will trip "check light bulb" warnings randomly.  At $10 each they are completely useless to me.  I replaced them with $0.50 LED CANBUS compatibles from China which work flawlessly.  I am returning these for a refund since they DO NOT work as advertised.

Hit and miss as to what vehicles it works on. it is unfortunate that you end up buying the device which says it works on all cars 1996 and newer but then you find out it works on some and not others.

I have used this on the followign cars that work: 2000 Chevy S-10, 2008 Mazdaspeed 3, 2005 Nissan 350Z, 2003 Nissan Maxima

I have tried it on the following cars that will not work: 2009 Mazda CX7, 2012 Chevy Torrent

I do not understand why it will not link with some but will link with others. The advertising is incorrect in saying it will work with all cars after 1996 that are OBDII compliant. I was forced to take the 2 cars it does not work on down to Autozone to try their scanner instead.

I have all the NFS game and they all work with my G27 Wheel this one does not. Don't make the same mistake I did and get it before finding out. Sold it on Ebay the same day

Works with a few cars, but it did not work specifically for a 2008 Acura TSX. I had to use another brand to connect with the TSX.

Even though it does not explicitly say, this DOES work with Nissan Sentra (mine was a 2004). I think it works with other models too, just google TYC 700046 to find the whole list.

My fan no longer sounds like I have a playing card on my bicycle wheel. It's great :)

Didn't work until a mechanic reprogrammed my TPMS sensors to my computer.  Kind of defeats the purpose of buying the tool...  Should be better if you have your factory set of tires that are already programmed.

I purchased two of these RC cars for my son for his birthday and after having them for about a week or so, he asked me to race one of the other cars against the other and thats when we notice the cars only had one channel on 2.4 frequency. This was the downside to having two cars from the same manufacture. Other than that the cars run smoothly and quit we just can't use the two of them at the same time because the remote will control both cars. If you purchase this product don't get more  than one.

A few reason not to get it . My biggest complain being not every hotwheels will work on it. In fact I tested all the hotwheels my son has and none works except the one come with the set. 2 el cheapo small cars worked but couldn't stand the abuse of the Turbo Booster .

Other than that the track is very high speed, and it fails about 1 out of 10 times even with the stock car. It hasn't shoot the car out that can harm my son but mother and grandma is very worried. Also the hand of the gorilla suppose to hit a lever and hummer the car into a car cage. But when I set the set on carpet the gorilla misses the lever all the time. It works better on kitchen floor but the manual says make sure to set it on "carpet". I guess it's going back to the store tomorrow.

I would had kept it if most hotwheels will run on the track. I bought it from Toy R Us and their display used just every hotwheels there is. I guess they never test it and it's very miss leading.

Didn't work in my car. Check website for compatibility.
