Perfect seat. Light and super easy to install or move between cars. So good I’m buying a second one for mums car.

Jenny Crockett

I found this booster very easy to install and it will fit my very tall 8 year old granddaughter as a full booster for a while yet and then will be used as a half booster for her until her younger brother and cousin need it. She has however complained that it is not very comfortable as it catches her across the top of her shoulder blades where the adjustable headrest meets the back piece. There seems to be quite a hard ridge just there and perhaps it is that she is just at that height that there is a problem however I was a bit disappointed with that part. Overall it seems a good seat for the price.

Awesome car seat

Well this is a brilliant car seat that will see my daughter safe and secure until she doesn’t need one anymore. So easy to install with the latch/isofix option. It’s a little wide for my Nissan Juke so I have to fiddle a bit when doing up the seatbelt but it’s worth for the quality. Great service from Winkalotts to WLG as well.

We needed to get a bigger seat for our 6 year old she is a bigger girl with wide shoulders this seat fits her so well and she still has more room to grow. The seat was very easy to install.
I definitely recommend this seat!!

4.75 *

Easy to install and adjust. Provides excellent support for our taller, slim 5 year old, with plenty of room left to adjust for growth. Seat seems to fit well into a variety of different vehicles while still sitting the child upright, with seat belt in a comfortable position. The top section does a great job supporting a sleepy child's head, without compromising body position. 5 year old reports it is the "comfiest booster ever".
Why not 5 stars? Within two weeks of use, some of the seat cover stitching has come loose. Not a deal-breaker, just a surprise to see, given the quality of the rest of the seat.
Definitely would recommend the Diono Monterrey booster, so if you are hesitating - go for it!

Love Isoki products

Great quality bag. Love the color. The material is nice . Easy to clean. Quite big but great size because it fits everything I need for my Toddler for playcentre or when going on day trip. Can fit a few changes of clothing, jacket nappies wipes lunch box. A drink bottle for both of us. wallet keys etc. Just perfect. Comfortable to wear on your back or hangs on stroller with the stroller straps easily even on my smaller stroller. Love Isoki I've bought a couple of there nappie bags already. Very happy with it. Great price and service fast shipping. Bag was as described. Very happy.

Great stroller

I love this stroller. The handle extends out nice and high, so no stooped backs when walking along (both myself and my partner are tall and struggle with other brands that are much lower). Sturdy construction. Good wheels for going on rough grass etc. Big storage basket. Good sized canopy for protecting against the NZ sun. It is quite heavy, but then it was never going to be a 'travel' stroller so that's ok. Really pleased with it overall.

Does the job

Reasonably sturdy and a good standard size for cups etc. Annoying how you have to remove it every time you want to collapse the stroller down. Sticks out sideways a lot too. I like it but don't think it wiill get used as much as I thought it would.

Purchased from Australia

Order process was smooth and item arrived safely by courier. I was not able to source this travel cot in Australia, I think due to Baby Bunting brand monopoly, and them not offering this exact cot. I wanted this slightly larger cot, than the Nuna cove air, as I think in the long run we’ll get longer use from the Nuna Sena Air cot. I am grateful to be able to purchase this product from NZ neighbors. Cot is as promised, easy to assemble and of great quality. A little trickier to pack away, but I’m hoping it’ll get easier with practice. Check out YouTube for product review videos and you’ll see why this product is worth the extra $$.

Fast and reliable

Amazing fast shipping and great product
