I haven’t tried that product, but I have tried the $50~ dehumidifier and it did not move my % down at all. I think the idea of products that small is they are to remove moisture when it’s quick and short bursts of moisture (like a bathroom, after a shower) or to be in super tiny places like under a sink.
When your plant is constantly putting water in the air, those little products can’t handle it.
If it’s the upfront cost, amazon typically has nice ones like a Frigidaire where you pay for it over time.
If it’s the electric costs, I only run mine at night when my lights are off for cheaper and more stable use.
