## Product: Blue Wave 12 mil Solar Blanket for Rectangular Pools
**Brand:** Blue Wave

The Blue Wave NS420 12 mil Solar Blanket seems to do a solid job when it comes to heating up your pool water. Here's a quick breakdown:

### Heat Retention

The 12 mil thickness is key here. It's got these thermal bubbles that are pretty great at holding onto heat, which can bump up your pool's temp by around 15 degrees Fahrenheit. 

If you live somewhere cooler, this could really stretch out your swimming season.

### Durability and Longevity

The manufacturer claims it's pretty sturdy, thanks to that thickness. While many people find it's robust enough, our research suggests that the longevity can be hit or miss. 

Some have noticed it starts to break down with the bubbles coming loose after a year or so, which probably depends on things like pool chemistry and sun exposure.

### Water Conservation

This blanket is also good at cutting down water loss through evaporation, supposedly by as much as 95%. 

That's a bonus for saving water—either because you're in a drought-prone area or just want to cut down on your water bills. Plus, less evaporation means you'll likely use fewer chemicals.

### Handling

Even with the 12 mil thickness making it a bit heavier, most people seem to handle it just fine. 

It might be a bit trickier than thinner options, but not too hard to manage overall.

### Conclusion

All in all, the Blue Wave NS420 does a great job at warming your pool and conserving water. 

Just keep in mind the potential wear and tear, especially depending on how you use and store it. Balancing its strengths with the possible durability issues could help you get the most out of it.
