This wallet?
It's for EOS and also the first time I've heard it. Why people keep using these unpopular wallets and risking their funds? use only the wallets that are verified and trusted by your network or the coin that you're using.
That should be it. Tried using, it says free EOS wallet so I tried but you have to pay 0.5 EOS. Not free at all.
The wallet is acknowledge by Newdex.io though which is somewhat a good thing but I didn't get to know how to buy CPU, NET and RAM from the wallet. They give away free CPU, EOS and RAM but too little to let you trade.
Last time when I used the EOS wallet on Wombat it was free to use without the private key and we can use that account for the dapps supported by the Wombat wallet where most of the frequently used dapps are listed.
If you want access to your private keys then you have to pay the cost to upgrade to some premium account for accessing the key then you will have full control of your EOS account.
Regarding the topic of this thread, they are legit as far as I know but I have used it long before say more than 6 months ago.
If you are a frequent user of the EOS chain then I would recommend having an EOS account with full access by paying for it or creating using others. You don't have to pay for RAM all the time only buy some if you don't have any RAM available. Staking some for CPU and NET is a must for transactions but if you have your own account then there are other ways to avail free transactions every day without paying for CPU and NET.
You could use REX for CPU and NET loans but it should be fine if you spend 0.1 EOS for CPU and 0.01 EOS for NET for making few transactions at the current rate
