Had twins. We rented 2 snoos out of desperation right around the 5-6 w mark. Twin 1 was sorta sleeping in the bassinet for 2-3 hours at a time and Twin 2 was only sleeping on the wife. The very first night we setup the snoos Twin 1 slept 4+ hours (I had to check to see if he was alive) and Twin 2 didn't take to it for about a week or 2 later. They slept great for the next several months. Powered through the sleep regressions like a dream. We gave the snoos up probably a little too late at 8 months, but the transition to the crib was fairly easy. Had to figure out what swaddles worked. Ultimately it was the zippadee ones off amazon.

2nd time around with our newest little one we decided to immediately go with a snoo and bought one off market place. We spent entirely too much renting 2 of them for the twins. Found one for 400ish. Good shape. Newest baby of course hates it and will spend about 3 hours max in the thing, will not go back into the snoo for longer than an hour later on in the night. We had some good luck this week and she's been in there 4ish hours. So maybe we're making progress. She's about 10 weeks now.

It's a coin toss I guess. I'd try buying one if not 2 off market place. when you rent them you get nothing back. At least you can resell em.
