Your baby has just outgrown their capsule and you want a carseat that will last them until they are ready to sit on the adult seat but you also want them in a 5 point harness the whole time! The Safe N Sound Maxi Guard is a harnessed booster seat which means it faces forward from 6 months onwards and your child will stay in a harness the whole time. It's not like a booster seat where you use the adult seat belt, your child will have a dedicated inbuilt harness which is unbelievably safe.
Most important features
- The harness is so simple to use and hassle free. Simply pull the grey latch up and the headrest and harness will adjust automatically for you - no more fiddling and unfitting the harness!
- Plenty of padding and cushioning is provided to ensure maximum support when your baby is still reclined. As your baby grows, just remove the padding and it will be still super comfortable but more spacious for your older child.
- Two recline positions to help the transition between rearward and forward facing seat.
-
Super easy to keep clean. The cover is quick to remove – there's no need to remove harness.
- The Active Head Restraint (AHR) has been designed to contain and protect your child’s head in a side impact crash. Deeper side wings shield and contain your child’s head in a side impact crash. AHR grows with your child to contain your child’s head minimising impact forces.
- Helpful rubber harness holders on either side to store the harness buckles in. We all know how hot these can get in the Australian sun so this is a great way to protect bubs from accidental burns

Amazing sealant and easy to use even in cold weather.
This product is amazing. It poured right into my tire even though it was -8 celcius. It sealed the crack in my aluminum rim and the the leaky tire bead after I hit a rock. Sealed everything and got me back to trailer and it is still holding air.

Go Ridding and Go Flatless with QuickStrike tire sealent
Size: 1 Gallon + Tool, Set name: Off-Road Formula
I’ve tried several tire sealants over the years on my ebikes and scooters, but FlatOut QuickStrike is by far the best I’ve used. From the moment I added it to my bike tires, I noticed a difference—it’s incredibly easy to install, and you don’t have to convert to tubeless to benefit from its protection. The formula is thin and spreads quickly, sealing punctures almost instantly so you don’t lose much air.
What I feel that really stands out is how effective it is. I ride my ebikes through rough terrain with lots of thorns and debris, and since using FlatOut QuickStrike, I haven’t had a single flat ( unlike before ). Even when I’ve picked up multiple punctures, the sealant has handled them all without a problem. I feel that the peace of mind it gives me is priceless, especially on long rides or commutes where a flat could ruin your day ( and It has in the past ).
Another big plus is that it’s a one-time application—it won’t dry out or turn into a mess inside your tire ( like that Green Stuff ). It’s also safe for both tubes and tubeless setups, and works well in my 20 inch and 14 inch tires. I’ve used it on my ebikes and scooters and the results have been consistently impressive.
Make me feel confident of the durability of my tires on my ride. I bought the gallon bottle because I have a few ebikes and scooters. this stuff works great!
If you want to spend less time fixing flats and more time enjoying your ride, this is the sealant to get. Highly recommend!

Fat tire savior
Size: 1 Gallon + Tool, Set name: Off-Road Formula
The best fat tire and dirtbike sealant we have found and love the gallon size. Pump clogs but clears with a strong push and love that it is water cleanup.

Worked perfectly for me. Sorry I waited so long.
Size: 1 Gallon + Tool, Set name: Off-Road Formula
I was clearing a field full of mesquite trees, and my tractor tires were getting destroyed. Mesquite has nasty 3-inch thorns, and I was plugging tires constantly. Eventually, all four tires were flat at the start of each day. These tires had been plugged more than 10 times each.
I bought FlatOut Quick Strike and followed the instructions exactly. The pump dispenses about 1 oz per pump, so I put 30 pumps in each tire, and the bottle was mostly empty by the time I finished. Typical with any pump dispenser it was also difficult to get the last bit out of the bottle using the pump.
It’s been a week now. One tire has lost about 1 PSI, but the other three are still holding exactly where I set them.
Considering how badly these tires were damaged, I’m impressed so far. This is the first time I’ve gone more than a day without dealing with flats in that field.
