One point to note also the manual recommends a brew time of 3 minutes with 1 scoop of coffee for me this is quite weak id suggest increasing each of those measures by 1

It hasnt caused any damage maybe slight bending but it doesnt feel very user friendly when it happens

Not that that detracts from the item really but look elsewhere if youre planning to make coffee for two people

One gripe is that sometimes after being submerged in hot coffee the plungerfilter seems to expand and drag against the glass as you pull it out
