Protect your investment.
Huge upgrade from the factory Vaira mount. Slight struggle to put it on, but that's how you know it's not gonna fall off. Protect your investment. Well worth the price.

Pretty close to the Garmin OEM, but a little diff feel
It seems pretty good. The clasp mechanism is close to Garmin's, but doesn't quite have the same feel and "click" as the Garmin. The seat post spacers are a little more rigid. I installed the mount on my secondary bike, so we will see how it goes for a coupe of weeks. It seems ok, but not identical to the Garmin OEM version.

One of the best mounts I've seen so far!!
The Garmin mount works very well. I have a "D" shape post on my Venge. I was a little concerned because the "D" shape adaptor that comes with this is too big by about 1/4" inch (see photos). BUT....it surprisingly still holds extremely well. The three bands keep it in place very well. You can still move it my hand from side to side, but when riding it hardly moves at all, and that's after riding on chip seal, cattle guards, and pot holes. It's tricky and very hard to get on if you are using the bands...so be patient with it. If you were to use the zip ties, it would go on very easily. But I was concerned about the zip ties leaving markings on the seat post stem over time and opted not to use them. Overall, I am very pleased and impressed with it. I have seen too many other Garmin mounts on my friends bikes fail and topple to the ground...but I have yet to see one of these fail. In the future...I would like to see a smaller version of the "D" mount adaptor for those of us with narrower seat posts for more stability. But aside from that, I would HIGHLY recommend this to anyone!!! I have 100% confidence in its performance.

FITS Garmin Varia RCT715
Im writing a review because I have read some weird claims on here about fitting. First, this absolutely fits the RCT715, like it says. I am not certain about this, but pretty sure it ONLY fits the RCT715. I just saw one review that said it doesn't fit "Garmin Varia," then clearly showed a picture of the 515. 515 is not 715, thus it doesn't fit. The 715 has a little knob on the back. This should not be a surprise, and it definitely isn't rocket science. If you have the light it was designed to mount, then it is a perfect solution for you. i used it because its cheap(er) and works well. I do not mean to imply it is cheaply made though. I now have multiple mounts on different bikes. I ride gravel all the time. its rough gravel too and I have never once lost a light with this. I've had just about everything else rattle off the bike, but not the light. Hope that helps alleviate some confusion for anyone curious about this option. Again, just look at the light you are mounting. If it matches what is written in the description, then you're in business. If you have a different light, then I'd not expect this to work for you.

Secure mount for your radar
Perfect for mounting my Garmin Varia radar safely to my seat post. Provides more security than the factory provided mount, and easily attaches. It also comes with rubber adapters to fit different seat posts in case I replace my bike in the future with a different seat post style.

Good idea just didn't fully work
These bands couldn't get around my Trek Madone Gen 6 Seat Tub; the provided zip ties weren't long enough. I ended up getting some additional zip ties to make it work. The mount itself isn't bad; it's stood up to a summer's worth of riding. I wouldn't buy this product again.

This feels way more solid than the RTL515 mount that Garmin provided. It can also be used with zip ties which makes it more secure. I think this is a similar design as the mount that is paired with the RCT715. It comes with several seatpost style adapters with both 77 deg and 73 deg angle options. Great product!
