OK guys, this thread is working great. It created quite a buzz in my email in box. Looks like we can expect some exciting videos!
I got some PM's inquiring about the mounts from Harbor Freight, so instead of individually answering here it is for everybody's benefit.
Yes, price is more or less $5! It varies from store to store and source of their supply (different vendors at different delivery times). It only varies $1-2!
Rated carrying capacity varies due to supplier as well. For example my dual cup handle has a sticker rating of 200 lbs, but the one below from the web site is at 125lbs. READ THE LABELS.
Dual and quadruple handles, BEWARE that surfaces on your car are not 100% flat as glass these handless were created for! Make sure your car is free of dust and dirt before attaching these and that you press firmly on each individual cup while clamping it before proceeding to the next! Carry microfiber towel, glass cleaner and spray detailer for painted body surfaces. It helps a lot! Handless are barely flexible enough (at least dual one is, I have no experience with quadruple one!) to attach securely to the hood and some more curvy areas. Doors are no problem at all.
I am planing on cutting a handle from my dual one and add pivoting joint of some sort to make it more articulate for curvy surfaces. Look into it yourself! It will make it possible to mount them anywhere.
Beware of the aluminum handle! It might be more durable (not necessarily stronger-suction depends on rubber diaphragm!), but it will be more rigid which will transfer more vibration to the camera and your video! Plastic handles and tripod ball mounts have some flex that actually works in your favor giving you more steady video. Crazy to some of you, but it is true.
Suction cups in general: stay away from simple suction cups that you just press on and pull off. They are not safe! Only go for press on & lever clamp down type which have much better clamping power!
