It's a good tank and it has awesome flavour coming from the coils, espeially the mesh coils but i've been using the Crown 3-tank more than this(i own the black version of Crown 4).
Imo, the Crown 3-coils are much better for fruit flavours but as always flavour is subjective as it should be.

It sucks when tanks are leaking!!
I recently bought the new Smok TF-tank and after filling it up it started leaking really bad through the airflow so i had to take the whole tank apart and put it together again, this time with no leaking. Those new Smok-coils, both for the Baby Beast v.2 and the Tf-tank were really good though, but Smok and other companies have been, and are milking the old baby beast for years now so new coils were well overdue even though i was surprised the new baby beast coils are meanr for higher wattage settings. The single coil didn't start to put out any flavour until i reached 90 watts so naming it a baby-tank is kind of misleading imho. Dual coil were grrrreat
at around 70 watts. Superb flavour and lifespan compared to the old school baby beast-coils.
Hope you managed to fix the leakage on your freemax mesh pro:)(Y)
The coils for mesh pro has a white o-ring/gasket at the bottom of the coil and they tend to fall off quite easily, which may have caused your tank to start leaking.
I've had that problem on my falcon-tank so it's not that unlikely but like i said; i hope you got it sorted out.

Sorry for the long "rant":)
