Works well and it pairs up with my phone, and cycling app. Sometimes the belt slips, but that might be an issue with any HR monitoring system?

It works as advertised. Is comfortable and seems accurate. If you need a Bluetooth heart rate strap this is a good value

This is my first hr sensor and it works well, but the strap is just a bit small for my chest, at 5'8" 175 lbs I wouldn't have thought this to be a issue, works well enough it's a bit of motivation to lose a bit of weight.

good fit and picks up my micro with no trouble. Nice to have heart rate all on one unit. This will help your training, even on the mountain bike.
This is a great option for connecting to Lezyne's GPS units. Works great, easy to care for & pairs easily. Pairs with Zwift using a phone app. Might be an issue for those with larger chested persons as it does not appear to get very large.
I've had two of these over about 3 years and they perform well. I've never had any trouble pairing them with head unit or phone, I've never had trouble with the battery running out. The one problem I did have was that a snap on the back that attaches to the band broke after two years. I bought a new one and had the same problem after six months on the new one. I emailed Lezyne support with a pic of the broken snaps and they replaced not one but both sensor units for free. They also said they had fixed the manufacturing problem on the snaps and this appears to be true. So not perfect, but very good support, great price, and very reliable.
Got my first one along with a Lezyne GPS unit. That one died because of a mechanical issue (perhaps not Lezyne's fault, but not very durable design). My second one just died without any warning signs or indication. So perhaps good value initially, a good fit, nice design and such ... But not durable.
I've been using this HR sensor for a few years now and have had no issues with it. It's simple to use and works good.
Works as intended and excellent price compared to other HRMs
