When buying an oil filter you have options. With Blackvue you are locked into playing their game or nothing at all.
The point with the tape is simply price gouging
Yes, it is price gouging.
There is a simple, more affordable solution and you are not, "locked into playing their game or nothing at all.". There are plenty of alternative options.
I've been using dash cams for 13 years now and I've experienced occasional problems with failed mounting tape since day one.
The tape pads that are supplied with dash cams are almost always
3M type 5952 VHB (Very High Bond) dual sided foam mounting tape. (or a similar variant). It comes in all kinds of shapes and sizes but is most commonly available in rolls. Dash cam manufacturers simply buy the tape from 3M and die cut it to fit their cameras but the tape is just a commodity item.
It is available in commercial/industrial form in different size rolls of different size widths and that is when you see it listed as "3M type 5952 VHB". There are different types of VHB that have slightly different properties and it comes in black or gray.
It is also available in a consumer form and you'll usually see it in packages that say something like "Scotch Extreme Double Sided Mounting Tape" or "Scotch Outdoor Double Sided Mounting Tape" and so forth.
Anyway, for years now, whenever I need to remount a camera I use my own supply of this stuff that I keep on hand. I happen to have a roll that is two inches wide but it has become somewhat hard to get in that width. If that is not available I use two pieces of narrower 3M VHB tape side by side. All you need to do is trim that tape to the size of your camera mount. It isn't hard. A sharp scissors is all you need. (Simplest method is to firmly apply VHB tape to camera mount and trim carefully around the edges with sharp scissors as close to the edge of the mount as you can get.)
The tape isn't exactly cheap but buying it yourself is way cheaper that getting ripped off by Blackvue or any other dash cam manufacturer. The product has all kinds of other unexpected uses anyway so it is good to keep a roll around. I always keep some on hand.
Here are a couple of links as examples but be aware that there are many, many options available. You'll find this product at Home Depot and practically any hardware store or big box store.
