OEM Hayward product in Hayward box. Installed and registered yesterday and my SWG is back in business. Product as described. I will do business with seller again. Thank you!

Received the wrong product due to the fact the seller described the wrong product. when asked to get the correct product that was described in the listing, they kept saying because of the price it was the correct product I received. They wrongfully advertised a different product and would not exchange when I called them out. Horrible customer service and still have the wrong product. Do NOT recommend buying from this seller.

The item was great! The package was very late and got lost in tracking. This had nothing to do with the seller. Dealing with FedEx was a nightmare. I think I’ll just stick with Amazon Prime from here on out just because of the terrible service by FedEx. Again, this is not the seller’s fault, but the package was supposed to be delivered more than a week ago and FedEx couldn’t give me any specific information as to how my package got lost.

As described, fast ship and GREAT PRICE! Seller shipped a genuine Heyward canister, not a knock-off. Will repeat for sure! Thanks so much!

The DX3 pool cleaner I received was a refurbished unit, mistakenly listed as New. It was nicely packaged in a new box and looked near new, but wasn't what I ordered so it was returned for a refund. There was absolutely no fuss involved, In The Swim Pool Supplies were very easy to communicate with and sent me a new unit via overnight delivery. I would suggest that their customer service is nothing less than superb.
