In my opinion in 2018 bike computers should be more evolved.

I have been using them since the '80s, beginning with the Cateye Solar. I have stuck with Cateye for a long time, dropping them a few years ago when all of their models had tiny displays with microscopic numbers.

Three years ago I moved to the Sigma BC 16.12 STS. I like the large numbers but little else. I have had to replace it once already, and the unit that I bought last summer no longer shows cadence. ( havr done a lot of troubleshooting). I am not going to spend $35 on a new cadence transmitter. Sigma's replacement parts are expensive, and they don't seem very durable.

I see quite a few nice possibilities, but they lack cadence. Apparently that's not important to many people.

I have zero interest in GPS or any kind of device connectivity. All I want are these features: Large digits, replaceable battery, simple, fairly rugged, wireless, and cadence.
Any recommendations? Cateye Padrone Digital Wireless? I notice that Amazon doesn't carry it for some strange reason. They also have some bad reviews.
Thanks.
