What to buy: Ultrafire WF-139 or Ultrafire WF-188?

[mOJAVEpROVIDENCE]

I think it's time to buy a new charger and was wondering which one of these chargers I should get for my AW High Drain 18650's. The WF-188 is $5 more and I want to know if it's a good idea to spend the extra money. If so, why? I appreciate your support, thanks

... because it charges every battery under the sun including the 26650.

... because you can charge 70 mm long batteries with WF-188
which you practically can not insert into WF=139

For that little of a difference I'd go with the 188, just a more versatile charger, selectable charging rates and you can charge 3.0 batteries with it if you get some in the future. I've had one for over a year with no issues.

I've also read some reviews saying that the 139 trickle charges which you don't want, don't know whether that's true or not and wouldn't be an issue anyway if you didn't leave the batteries in the charger after the charge.
