I live on a highway and it's been working well; however the plow did break it during a very wet and heavy snow, 24". The seller was very responsive and is shipping a replacement item.
Must Get!!!

Got tired of replacing my post and I refuse to place a barrier fence next to it, so I decided to purchase snoflex. I figured if anything it will help. The unit is well-built. Rugged cables and hardware. Easy to install (There is an error in instructions regarding drill bit size for pilot holes, I used 1/4" bit). Worked very well against snow last week. So far so good. Highly recommended!
Solid product built in the USA great customer service

I bought a Sno-flex after looking at several different options for ways to keep my mailbox from getting destroyed every winter. I was looking for something permanent that I would not have to replace or take down and put back up year after year. Out of everything I found, this seemed to be by far the simplest and most practical design.
I ordered it directly from Sno-flex as it was not yet available on Amazon. I received it the very next day after it shipped and was immediately impressed by the quality and how solid it seemed. Installation was easy until it came to drilling the 3/8" pilot holes as the instructions state. After drilling 2 of the holes, I quickly found out that 3/8" is too big for the lag screws that come with it. I ended up having to get 5" bolts to go all the way through from one side to the other and secured them with locknuts. For all the other holes I used a 1/4" bit and the lags held nice and tight so I'm sure this was just a typo in the instructions.
Once installed, I noticed the top half of my post with the mailbox on it sagged slightly towards the street. I emailed Sno-flex and received a phone call from them the very next day. Matt from Sno-flex came out to my house to look at it and it turns out the metal mailbox I was using was too big. Although it only weighed 9lbs, Sno-flex is designed to be used with standard size plastic mailboxes only. The Sno-flex itself was also twisted slightly and Matt swapped it out for me on the spot with no questions asked. I swapped out the mailbox for a standard size plastic box which weighs 4lbs and the sag is gone with my post back to vertical. As I stated above, I am very pleased at how well constructed and sturdy this thing is. Although it has not been through any really heavy snow storms as of yet, I am really curious as to how well it will hold up. Based on first impressions I would suspect very well and if there are any issues, Matt and the people at Sno-flex are very responsive and customer friendly so I'm sure I won't have any problems!

Daring the snowplow to knock THIS one down!

Every year, I replace my mailbox and repair the post. Usually, the arm gets knocked off. I've tried bolting 2x4's on either side. This year, the plow took the post off at the base, and I had to replace the whole thing. I came across the Snow Flex mailbox spring and had to try it. It was very easy to mount, just make sure you take enough off the new post to make up for the length of the spring. It works perfectly!
Very srurdy

Very sturdy - we'll see how well it works when the snow plows get busy.
