I did 3 months when LO was 6ish months old. The stuff was great, it was good quality and items well suited for her age. The biggest problem I had was getting repeats of stuff or stuff that was very similar to what I had. I think in every box I got 1-2 things that I already owned which made it not worth it for me.
We received a 2-month gift subscription from a friend when LO was born. Personally, it was a sweet gift, but not something I would purchase for myself. The items are definitely age appropriate and good quality (Melissa & Doug, Honest Company, Boon, etc.), but we received items we already had or wouldn't necessarily use - just adds to the clutter I am desperately trying to reduce. If I had the extra money a month to spend on LO I would probably go to the dollar/toy aisle at Target or put the money in his college fund. The surprise factor was definitely fun, that was cool.
