Onekey classic 1s pure. I use it in combination with the sparrow wallet.

Sparrow. If you meant signing device: nostr:nprofile1qqs09jtvjlmyrxjn37zv70a89csegcz7rpyqjmnw29cveedhv7vagqqpzemhxue69uhk2er9dchxummnw3ezumrpdejz7qg4waehxw309aex2mrp0yhxgctdw4eju6t09uq3zamnwvaz7tmwdaehgu3wwa5kuef0x9u2rf

sparrow paired with a coldcard or a seedsigner covers both software and air gapped signing, hard to go wrong with either setup.
