Enova or Opus charger?

I narrowed my choice down to these two chargers. The Enova Gyrfalcon All-44 and the Opus BT-C3100 (mainly because of the popularity on this forum). I need a charger that can handle NimH/Li-Ion and has at least 1A with 4 slots occupied. I like that the Opus has internal resistance check, but HKJ’s review says that the charging is not optimal due to pulsing. Any comments on this? Doesn’t seem to be that big of a problem since it’s rating is still pretty good?

Zanflare C4 also have internal resistance feature.

Yeah that also seems like a possible candidate…hmm. Alright I ordered the Zanflare C4. 19 Euro seems like a good deal.
