yes/no and why

no because no

No

Waste of gold and you don't get the effects of biscuits for them

Just buy regular pots

like we already studied
3600gold for 65AD and crit bonus

or 2*1300gold for BF swords 80AD
so itemspace pretty OP, also considering boots or cdr items or nice passives like sheen

a vampire sceptor not always is a good item
same for a doran blade
if you seak a nice powerspike in the mid game, like a 45cdr ezreal with muranamana/icebourn/2*BF sword

then a refillible potion is best for lvl1-9, togethor with a startitem that builds into something deccent
better then a doran
if you combine it with a few nice runes
and then its better to sell the potion for your 2nd BS sword
then having a doran, upgrading your 1ste BF sword, then sell doran, before get new BF sword


refillible potion+anything>doran meta craps and 66.6%more costing life potions

no its not worth
Should only be bought on junglers with decent early clears who can afford not to get a 3rd potion

Refillable potions healing is not significant enough to be better than the raw stats that you get from a Dorans blade
Buying it any time besides your initial buy is cost deficient

tldr no

I know it's situational, but for most junglers excluding shaco, I usually can only clear half the jungle + scuttle with refillable pot. On a typical jungles. Do you go for full clear or back after half clear and buy the machete/mana regen thing?

You don't get doran blade

Why are junglers upgrading their pots ?

buy a bead with shaco

Yeah.. I see that all the time and I think wtf.

Why spend the extra gold and that junk
