Poor head support


My newborn’s head flops around dangerously. Its installed correctly but we now have to reinstall it with towels to try get the seat to tilt back further. I’ve never had this issue with other branded capsules so very disappointed.
The buckles dig in to his little legs and the sun canopy is useless.

Faulty brand new and have to take for repair


Purchased this to go into the click and go adaptors on my city mini GT. Capsule itself looks great however we have just attempted to click in into the adaptors and it doesn't unclick unless you take the adaptors off the pram tip it upside down and force them out. After calling i was told it sounds like an issue with capsule itself as it should easily click in and out (which it did on the in store version). We were told we will have to either be without the capsule while its repaired or drive it 1hr plus away for repair if they have stock. It's a BRAND new capsule!!!! Not ideal with a 3 day old baby and 2 older siblings.

At first it was alright but after a couple of uses, the buckles got stiff and were a pain to use. Wouldn't recommend, unless your budget pleads you too. It's a pretty one though, in terms of how it looks and feels, my kid was very comfortable in it when we first got it.

Doesn't last long as too heavy


If I had my time again, I wouldn't buy a capsule.

Capsules are so heavy, especially with a growing baby in them. My mum was right!

We stopped pulling ours out of the car at about 8 weeks, so it was a big waste of money. It is just too heavy. You couldn't take it shopping or anything (even from week 1)

Better off buying a baby strap on carrier (like "baby bjorn" or a "baby k'tan") and a 0-4/0-8 years car seat. Would get so much more use out of both of them.

**My baby is now 7 months and have only just realised the capsule doesn't face forward. My average size 7 months old is also, almost too big for it (her legs hang out a lot and the straps are tight)

Difficult to use


I have had the same experience as Heather below. One strap always looser than the other - on closer inspection it appears one strap is installed differently by the manufacturer. An option would me is to try and twist it but this won't budge obviously because then it wouldn't be safe. Everyone finds it too heavy on its own to carry let alone with a 7kg five month old and growing. Same as Heathers review with the sun shade issue as just falls off all the time. Worst thing is that one strap is always looser as I am forever trying to find balance between too tight and too loose. Not worth the price tag - would rather have had a cheaper lighter one without the strap issue.

Wouldn't buy it again


Not the greatest capsule. It's ok at first but definitely will not last until baby is 1 year old as advertised as babies would be too long for it and to heavy to carry by the time they are 6mths. If I could turn back time I would have bought a much better capsule,with a higher safety rating and probably would have got it cheaper! After a while it become hard to click in and out of the base. Cannot be forward facing.

Shade come off easily, isn't very stable in car, it only last until baby is 6mths old not 12mths as advertised, low safety rating

Which adapter do I need for it to fit the steelcraft accent stroller? I've watched videos of it being attached without adapters but when I try it's very unstable

Hi Jessica, thanks for your question the Steelcraft Accent stroller doesn't require adaptors however you will need to remove the adaptors from your Britax Safe-n-Sound Unity capsule to allow it to fit correct.
