Hello,
I have the Oneida 35G drum and the sensor/flashing light to alert you when it's near full,,,but it doesn't seem to be reliable. Not sure why, but I've had it flash red when the drum was was only 1/2 full, and fail to flash red when it was over the top full,,,, I'll keep trying to adjust the sensor, but I was wondering if anyone has found a 35G drum that you can see through (? heavy plastic) or found a way to modify a steel drum so you can see how full it is-- low tech!
Thanks!
