I bought this product for my daughter for Christmas. As I went to install it on Christmas Eve, I discovered that the anchor sleeves that are included were a JOKE. The mounting bracket that comes with it has holes that are 2” apart. Knowing that the 2”x4” support beam is installed vertical (aren’t they all?) and I only had a 2” wide beam to screw into, I realized it wouldn’t install into the beam. So I rotated where the holes would be making sure 2 of the holes would go into the beam and the other 2 would go into drywall. These particular anchor sleeves are wider at the top creating a hole too big for the product to securely grab on to, even when expanded. You can’t predrill the correct size because it’s bigger than 3/8” and smaller than 1/2”. Try shaving it to be bigger and if you shave too much of it you are out of luck.After 2 hours of trying everything I could, I gave up for the night. I did my homework on YouTube and found that other swings use 1 Screw Eye to screw into the beam. Luckily, a neighbor had one about 3/8” x 4 (especially since the hardware store is closed on Christmas). By the way, the product I’m talking about is about $5 at Home Depot. I screwed that through the drywall into the support beam and viola!The actual product is VERY nice and durable. The bottom has an inflatable cushion and they send you a manual foot pump, in case you don’t have (an electric) one. The interior lights have different colors. The battery pack requires 3 AA batteries.If anyone from the manufacturing company is reading this, CHANGE THE HARDWARE TO ONE EYE SCREW! It will save time and heartache to your customers. Your manual doesn’t talk about pre-drilling the holes and what size drill bit to use. You are welcome to contact me if you would like to discuss my experience. Again, GREAT product, just change out the hardware for those who are installing it in their ceilings.
