Is this a new booster?

[John_]

So I just happen to see this red haifu booster on aliexpress, https://a.aliexpress.com/_Ev7GSlU, has anyone tried it or know what it's about?

2014-2018 year. They charged for National booster around 100-200$ but they made billions of them and they didnt sell them so they put them again. They are the most toxic boosters, your rubber has 2-3 weeks

It says "adhensive" so must be glue
