Instant ETH is an Ethereum faucet letting you claim up to every 5 minutes. You get a bonus just for signing up when you first create your account!
Instant-ETH.eu gives you chances to multiply your claim by up 300% by combining the multiple different bonuses they offer.
They payout to your Ethereum address after you've reached 500,000 Gwei. Supposedly, they are working to transition over to accepting FaucetHub and lower the payout mins.
