Heart Rate Monitor USA Replacement Soft Transmitter Strap (Works with Polar H1, H7, H9, H10 and Polar Wearlink Models) Size XXXL

Polar charges $39 for their XXXL strap. And this one works perfectly fine. My Polar H10 snapped right in. It is adjustable. No straps hang if you make it as small as it goes. Has a hook to take it on and off.I've only used it for a little over a week so far, but have had no problems. Will update if I do.

Product looks like a good and inexpensive HRM replacement strap. I have a Garmin ANT+ HRM transmitter and it works with this strap. I am replacing a POLAR strap, which also works. My only negative on this product is the sizing. My size is 43, which for POLAR is on the border between the M-XXL and XXXL. I tried this XXXL thinking it was the same - it was large enough for two people! I returned for a size M-XXL and it fits.PLEASE PUT A SIZE GUIDE OR #INCHES IN THE PRODUCT DESCRIPTION! IT WOULD SAVE ON RETURNS.

It has taken a while to find a heart rate strap that will fit comfortably. This one is very accommodating and works great with the polar device that just snaps onto the front of the strap. Be sure to measure yourself though, as this is very large and may be too big for some.

I purchased both the Med/XXL and the XXXL size. The two are significantly different from each other. The XXXL is a whopping 70" long and the Med/XXL is 38". Both can be adjusted from their full length to between ca. 26"-38" for the Med/XXL and 41" to 70" for the XXXL. The XXXL has a thicker and stronger band material, but many people will not be able to use the XXXL out of the box. If you (or you know someone) are at all handy at sewing I would recommend going with the XXXL and cutting the band to a more manageable size. Make sure you cut it on the end away from where the monitor clips on! If you are small framed you might prefer the lighter Med/XXL, but I prefer the sturdier band on the XXXL, especially given that the new Bluetooth monitors are a bit bulkier than the old ones.Heart Rate Monitor USA Replacement Soft Strap (Works with Polar & Garmin Transmitters) (XXXL)Update: As other reviewers have said the Polar H7 does not fit properly on the Med/XXL belt.

The polar strap that came with my Polar H10 was just an inch or two too small. For $14 this works perfectly. 6 months on and no issues and I use it every day for my 45 min workout. Polar wanted WAY too much. On this strap I actually have it set pretty small but it has ALOT of room to expand even larger if you need it.

I'm bigger than I once was, the original strap felt like I was punishing that elastic band for my failures.This one says it fits from 46 to 77, I am less than half the median and it fits perfectly out of the box with enough tightness to hold the strap in place and not make me worry about slipping.The original strap had a push button click buckle to keep it together, this one has just a hook that slides in a hook sewn into the strap. Hopefully that hook is secure, so far no problems, but only used it a couple times so far.

This strap doesn't stay connected as well as the original. Otherwise it is comfortable, and plenty big enough for my 360 pound body.

No reason to spend more on a strap. This one works just fine.
