I've been using my iPhone 4 with a mount to an air vent, but wanted to finally use the iPad (1st gen) in the car but could not find any iPad mounts on Amazon with decent reviews. I finally did a generalized internet search and then discovered that the brand RAM was reviewed favorably by an outside review website.
Luckily, Amazon does sell the RAM iPad mount and it has exceeded my expectations.
1. Very strong suction mechanism - The base of the suction is a rather strong, and large cylinder with a lever that one rotates to create a very powerful suction
2. Wide range of positioning possible in the 2 ball joints - There is a ball joint at the suction and another one attached to the iPad cradle which allow a very wide range of positions.
3. Extremely strong locking mechanism for both ball joints - There is a lock that one twists on the arm which will simultaneously lock the positions of both ball joints. The arm is made out of metal.
4. High quality plastic is used for the cradle/holster for the iPad which is very strong.
5. Fits iPad (1st generation) perfectly - If you have an iPad 2, there are two small rubber bumpers which you apply to the cradle/holster to allow for the thinner iPad 2 to fit.
1. You have to attach the cradle/holster to the arm with 4 screws and locking nuts (which are supplied) which took a little more effort than I expected. 1 of the locking nuts had a defect.
2. The arm is not long, which is reasonable considering the weight of an iPad, but it results in having your iPad close to your windshield. This may not sound like a significant problem, but it results in having a large percentage of your needed visibility obscured by the iPad, which looks gigantic when attached to your windshield.
This iPad mount is pure quality and awesome in its strength of suction. The construction uses joints made out of some sturdy material and a metal arm with a great locking mechanism. I have used it without it falling and even attached it to the moonroof so that it displays near the car ceiling so that backseat passengers can use it.
The greatest negative, is that the arm is probably necessarily short, causing the iPad to block what seems like a shockingly large part of your visibility. I never realized how large the iPad is until I saw it blocking my vision. Think carefully about how large the iPad is and try positioning it in your car behind some part of the front windshield and ask yourself if you can really tolerate this before purchasing this mount.
Otherwise, this is an excellent, high quality mount that actually works in holding up a large and relatively heavy iPad.
