After our original spa cover was accidentally damaged by one of our kids, we reached out to Larry Lewis and his team at MightyCovers.com to order a replacement cover. We decided to upgrade to the Thermal Guard Premium Custom "Walk-On" Spa Cover and are so glad we did--much more energy efficient and so solidly built! Larry's online Measuring Form clearly told you how to measure for the proper fit and placement of tie-down latches, etc. Larry called to confirm everything with us, placed the order, and the cover was delivered in a very reasonable amount of time. The quality was excellent and it fit perfectly. Larry and his team's customer service at MightyCovers.com is outstanding. They truly want your business and go above and beyond to earn it. For any other outdoor covers we might need in the future, MightyCovers.com will have all our business. You will be very pleased with your entire experience purchasing from MightyCovers.com!
