Last updated 31 July 2026 · How we score products →

Price history

Not enough yet to tell you anything.

3 observations, recorded 28 July 2026. We have 3 observations over 0 days. We need at least 5, spanning at least 14 days, before a range tells you anything. Nothing here is a trend yet.

We have no price feed, so this fills up only when someone re-checks the listings by hand. We would rather show you an empty clock that started than a chart drawn from two points.

Something wrong here?

Keep rate

No outcome data yet

We ask everyone who buys through us, 6 and 12 months later, whether they still use it. We’ll publish the answer here — including when it’s bad.

No one has told us how this worked out yet. No score on this page is affected by it yet.

Purchases are recorded in this browser, and on the server only until it restarts. There is no mailer yet, so no follow-up will actually arrive. We publish a rate at 30 answers and not before — a percentage from three people is a made-up number.
