Does it depend on any adhesive of suction ?

No! It is relatively heavy and has a non slip bottom. Stays on place very well.

No adhesive or suction. Just a low center of gravity and a nonslip base. I've driven pretty aggressively in my Porsche with it and an attached iPhone on the dash and it hasn't fallen off yet

No it does not. It has a very very fine felt like material on the bottom that grips the surface. It works perfectly.

Yes it does, it is extremely sticky but does not leave anything behind when you remove it.

Yes, granted you don't add any adhesive or anything else. Just unscrew the hand screw enough to release it from the platform you have it attached to.

It sure does. Like most products like this, you have to wet the suction cups. It works great.

It is entirely dependent on glue. I've had no trouble with it staying attached.

I do not believe so. I actually have been having trouble keeping it on relatively stationary items. (The adhesive gave out for me after about 6 months)

No. It's a suction cup and needs hardened material to get the seal needed to stick

I have not noticed any difference in suction, but I'll pay closer attention next time I vacuum to see if there is! (I'm guessing it's a minimal difference, if any, if I haven't noticed it!)

It relies 100% on suction alone, they give you a clear plastic inline guage so as to adjust suction for "optimal" performance. Hope this helps.

Yes it does and please make sure that you clean the area very good before using it, otherwise it will come off in a couple of days/hours.

No. It would have to be a plastic or glass surface for the suction cups to work

It does if you use the attachment head that is included with the vacuum as it has an adjustment setting for this purpose.

No adhesive....it's like the protective plastic that's used when it's brand new.....never used, however, it is more substantial, always stays in place and fits so well you hardly notice it's there. If applied properly it should last a long, long time.

not at all. in fact since the filter stays clean the suction stays strong. the unit is worth every penny.

Sure, its actually ideal for the suction. Just as long as the surface is flat or slightly curved without any wrinkles or bumps.

Yes, but if you ever remove it make sure to have some strong adhesive remover handy.

It has suction cups... So I think it should stick to any hard surface but I'm not sure.
