Kill Switch, No-Logs, and Device Limits: What to Check Before You Pay
The VPN features that change what you are buying: a kill switch, a no-logs claim, how many devices can connect, and the refund window.

A kill switch is about the moment the VPN drops
Encryption only covers traffic while the tunnel is up. If the app disconnects on a café network, some devices will keep sending traffic in the clear. A kill switch is supposed to block that traffic until the VPN reconnects. It is one of the few features that matters on day one, especially on a laptop that sleeps and wakes.
The name is not a test. Look for a setting you can turn on, and try it on a network you control before you rely on it while travelling.
“No logs” is a claim, not a feature toggle
A no-logs line means the provider says it does not keep a record of the sites you visit. You cannot see that from the app. Stronger versions of the claim mention what is not stored, how long connection metadata is kept, and whether an outside auditor has looked. NordVPN is the provider in this set with independent no-logs audits called out on the card. Treat every other “no logs” line as the company’s own statement until you have read it.
A VPN also does not replace HTTPS, and it does not make you anonymous. Your ISP sees a connection to the VPN. The sites you sign in to still know it is you.
Count the devices before you pick the cheap plan
CometVPN lists unlimited devices. NordVPN lists 10. LockNet VPN lists 5. DombayVPN is built around its own apps, mainly mobile, with desktop apps called out on its pricing page. A low headline price is less useful if a household needs more connections than the plan allows, or if the apps do not cover the TV and laptop you actually use.
Then check the refund. CometVPN, LockNet VPN, and NordVPN list 30 days on this site. DombayVPN’s guarantee was not confirmed from the public listing, so the card does not invent one.
The numbers come from the same price list as the VPN plan comparison. Read the comparison method before treating a card as a test, and use corrections if a checkout has changed.
