I have the Double Park by Cytech. I've had it for almost two years without incident. This is very easy to use and servicing the car is even easier! The only drawback is if you do any work near the side underneath, because the ramps can hinder the area. I have a jack-bridge which allows the car to be on stands while in the air. That's cool feature. I have aluminum ramps (a must) and a dolly wheel set to move it too. Moving is easier with a car on it as I've done this and it can be done with one person. I do recommend doing a check once in awhile just like you do your autos. I had a false panel put in the garage door and then made the door track go right up to the joists. If you need pictures let me know. Here's a picture of the rack in use.
