This sticks to my Chrysler Pacifica!
I bought a new-to-me Chrysler Pacifica and of course wanted a phone holder or two for when my husband and I are travelling. I absolutely adore the car, but I've never had so much trouble finding a phone holder that would stick to the dash, no matter how thoroughly I cleaned it with alcohol! Finally found this one, but it only sticks if you do NOT activate the suction part. That pulls the sticky part off the dash. And it's not very attractive on top of the dash. I'm more concerned with function than appearance so I'm happy with it, and it works great. The phone stays put and stays charged, which is all I ask.

Imperfect, sometimes charging is unreliable, clamp needs power to work and annoyingly not auto
The build quality is great for the price. Like iOttie. The tech advancement is cool but it doesn't work very well which is a disappointment.
It doesn't charge my phone very fast, because my phone is limited to 15 watt wireless charging, but it's great for preventing battery loss while using GPS.
The button to manually clamp and unclamp are a little too hard to press, it flexes the whole holder, so you need to press with your whole hand supporting the holder.
Sometimes my phone disconnects and reconnects randomly to this charger multiple times. Not sure if it's the charger or phone but that stinks . (I'm using an Anker 50w USB adapter for this wireless charger)
The clamping is motorized which is cool, but it's honestly less reliable than a spring loaded clamp because it doesn't always auto clamp the phone.
When this clamp is working properly it is great as it auto clamps onto a phone it's charging. But the issue is it doesn't always clamp.
It sometimes thinks it's clamped, when it's not, so you have to press the manual activation button twice so the phone will be locked in place. It's hard to know when you need to press just once or twice.
(The reason you press the button twice is if it thinks it's closed when it's actually open. Then you press first to "open" the clamp, even though it's already open, then press again to close it.
But if it knows the correct clamp position already, and just refuses to auto clamp, you only press the button once. If you press twice, you will end up cancelling the clamp. It feels random and unpredictable what the correct action is)
The clamping requires power which is another disadvantage to spring loaded hand clamps. But unclamping works without power due to a backup battery.
(Powered clamping is still better than those manual squeeze clamps, which are finicky to get a strong enough clamp on the phone)
I'm not sure how safe the battery is in a super hot car, like Florida heat. It seems fine for Pa heat.
