Solar Sun RingsNEW Sunburst Design 1 Pack

No calienta el agua. Se infló según indicaciones, se tuvo con un sol de 40° y no calentó el agua

No me gusto por que su funcion principal no la realiza, estuvo expuesto a la luz solar directa mas de 8 horas y no genero ningun cambio en la temperatura del agua ,si fuera posible calificar sin estrellas la hubiera dejado sin ninguna. Es un simple flotador en una alberca mediana.

These work so long as expectations are realistic. I'm in my 4th season using these rings and they do the 2 things I purchased them for: 1) reduce evaporation, and 2) retain a good amount of heat at night. They are significantly easier than wrestling with the blankets. If anyone purchases them for the sole intent of heating a pool, then you will be disappointed any likely quite angry as evident in reading many of the 1 star reviews. Are they overpriced, yes. But any product made exclusively for pools are way overpriced. I was just away for a little over 2 weeks. To ensure I didn't loose any if we got storms/high winds I put a leaf net cover over the pool and had the pump on a timer. Got home to clean water with little evaporative loss and the chemistry was good having treated and tweaked it before leaving and tossed in 2 chlorine floaters in. I know 4 stars is a bit of a stretch given price and somewhat cheap construction, but they do accomplish what I want out of them. Plus, most importantly is that my wife doesn't have to endure listening to me yelling obscenities while wrestling with a solar blanket 😳

Don’t notice a difference in temperature in my pool and instructions were difficult. Looked at a few how to online videos and you can’t inflate it too much and for the cost, I found it ineffective and expensive

Not fit for purpose
