Little Lamb bamboo pocket insert

Has anyone tried it yet? Its not cheap, but looks like it offers a lot of absorbency...

I have one of these with a small little lambs pocket nappy. I am fairly new to pocket nappies and am in two minds about the bamboo insert.

Pros:

It is nice and soft,
You can fold it to your desired shape (which means it will fit into any pocket nappy)
It is slim even when folded

Cons:

Doesn't seem to last too long on absorbancy - I use it in a small swaddlebees nappy on it's own and is drenched after less than two hours. In bigger nappies I use it with a microfibre insert which makes a great combination.

Hope this helps.

Im new to nappies, but would the night time boosters from little lambs not also work to stuff pockets with? they are even cheeper http://www.littlelamb.co.uk/itemdetl.php/itemprcd/Bamboo-Night-Time-Booster

I do have some of the nighttime boosters, so I am familiar with them. I was just wondering about the inserts, if they are really so much better than the booster?
