Ltc4311

Has anyone used an LTC4311 (adafruit.com/product/4756)? Did it help extend the I2C bus?

I, anecdotally, hear people complain about I2C not working well at long distances in drones. I bought one of the Adafruit modules and tested to simply see if I could communicate with an I2C sensor (BME280) with several lengths of cable. In a bench environment, I didn't notice any improvement of the LTC4311 over using pullup resistors - they both stopped working around the same distance. Trying to decide if I should spend more time evaluating the LTC4311.

Thanks!
