Have been using Electrum for almost a year now and haven't had any problems with sending or receiving coins. No issues with using it from me and haven't heard anything out of the ordinary happen to anyone's coins either.
Only thing I would like is not having to pay tx fees but that is normal for a client based bitcoin wallet.
Atleast they allow to pick what you want to set the priority level (economical*very slow*-top priority*fast*) of the coins right before you confirm you want to send them.
open electrum => tools => preferences => set transaction fees manually
Once you start to create a transaction, you can chose your own fee, and i'm pretty sure 0 fee is an option (untested)...
HOWEVER: use with extreme caution!!! not paying a fee might cause your transaction to be unconfirmed for a very long time (if not forever, or untill the network forgets about it). You do not pay the fee to the electrum developer, the fee is to give the miners an incentive to add your transaction to the block they're mining, cheaping out on the fee (or not paying a fee altogether), takes away their incentive to add your tx to a block, and might cause you a major headache (altough, there's a small chance you might be just fine).
