No, but I was thinking about ordering three of them. But I was waiting for someone on here to buy one and measure the difference in size between the two crotch straps, and post it on here. I want to see if it's even worth the money to buy the longer straps.
I do have the Dry Seats, the wider buckle tongues, two carry straps, and one carry bag! lol The Dry Seats was great at the beach, I was able to put DS in the Radian for the quick drive back to the condo in his damp swim trunks. I also used it when I had to drive him to the ILs when he had a bad case of diarrhea; I was scared of a diaper blowout in the seat! lol
Wider buckle tongues make a big difference, IMHO, when it comes to sliding along the harness straps. I can buckle DS in more quickly because the wider buckle tongues slide along the harness more easily now. I haven't yet used the carry bag, but the carry strap is pretty convenient and comfortable; it's got a decent amount of padding for the shoulder.
Please keep us posted on why that part of your order was canceled!
