I treat my snake plants like my African Violets. Both like to be root bound. If roots extending out of bottom holes of planter, I put plant in slightly larger pot\ planter. I trim roots a lot so repotting not required for another year. I put my three assorted snake plants in 4 inch planters.
The proper watering for cactus & succulents is a mystery in spite of advice from experts. Out of frustration, I did trial & error methods. I settled on watering the the soil with a sprayed bottle once a month on Sunday. I spray lightly around the center of the plants where roots are. This has been working for me so far. I'm not saying this is foolproof. Use caution!

I experienced a similar situation with fans n never received a refund or conversation from anyone. I was stuck with useless broken products. I only purchase what is returnable now
