Power 25 watts is very small. I am only satisfied with power 80-100 watts on one softbox.
Perhaps you bought it for some specific purposes.
How much dollars does it cost?

I paid $322.00 /i have 15 % off from regular price/.
If I am correct it was 45 Watts each. Not mega power but great for studio work with some smaller products and also some photography/video
in customers places like restaurant/food photography and many other things. I am sure it is also great for quick interview.
Yes 100w is great, but with soft box is not really great for smaller space and not easy for travel with them. I also love softboxes I am using two with my larger flashlights and other one with video light.
Every tools is for something.

I paid $322.00

I think you can find something similar on Aliexpress for much cheaper.
I would only pay that much money if I had a lot of shoots planned with models.
