I bought this product because I do not like plastic or silicone sleeves pockets and I'm not disappointed the contrary. It is very easy to use and almost loses none of its preparation. The large volume of the tube is more than pleasant and the fact that you can buy in replacement and keep them cool. There are also additional sockets of different sizes and shapes. It would have been nice to have more than two in the box because they are large enough to provided the precision of pastry. Regarding the macaroons with a little practice, you'll quickly get the hang of it to make it perfect.
