It's better than the Link 10, as it will always display status and it will use the same shunt/wiring, and fit in the same hole so your installation will be as close to "plug and play" as reading the directions.
You can keep the new shunt as a spare (not that I've ever heard of one of those going bad) or if you do the new install and find the LinkLite is still getting screwy readings you'll know your problem was either shunt or wiring, and you can put your Link 10 on eBay without the bad shunt (or keep it as a spare)
I found the Link 10 was not very reliable and mine also would get screwy readings after about 3 years in use. Resets didn't help. I replaced mine with the XBM but that's not being made anymore either, having been succeeded by the LinkLite. The XBM was a worthwhile upgrade.
