The title is a bit misleading. I found 0 flaws with this product. It's not perfect because this isn't the best tool for the job. But it's all about cost to value. Realistically I'd need plumbing for what would be perfect. But Almost perfect for under $20 is far more realistic. The 5 gallons can be a bit heavy when all the way full but that's it. Besides that this is just the cheapest, most basic, large water container I could find. I'd spend at least 50 to get something similar. Why it's 5 stars. As long as it's under $20 (though maybe not in 5 years, inflation and all) it's worth 5 stars.
