[Important Update on June 20, 2013]
My initial impression on the IQ-328 was most positive (hence the original 5-star rating). However, I have now determined that the design has a serious thermal limitation. When charging 4 cells at 1000mA, it may trip over-temperature protection and shutdown. So I have to reduce the rating to 3-star, meaning 'It's Okay'. But I can no longer recommend it over the BC1000 or BC-700.

I used an Infrared gun to measure the battery temperature during charging at 1000mA. A few cells reached ~60 degree C and tripped thermal shutdown. This by itself is not a big problem since it shows that thermal protection is working. But after I removed the back cover of the charger, I detected several 'hot spots' (around 70 degree C) on the circuit board right under the battery contacts. So the charger is actually sending heat through the batteries contacts, causing the batteries to over-heat. This is just bad thermal design! In contrast, the BC1000 also has hot spots on its circuit board, but the heat is directed away from batteries.

I should point out that: although battery at 60 degree C is too hot to hold, it is a far cry from 'Fire Hazard'. The charger still works correctly if you don't exceed charging current of 700mA. Or you may use a fan to blow the heat away from batteries.

After much research, I decided to try this AccuPower IQ-328 Battery Charger Analyzer Tester AA AAA NiMH NiCd. So far, I like it a lot.
The main reason I chose this unit over its main competition (namely, LaCrosse) is because the latter received some damaging reviews due to durability.
I can't attest to the durability yet. I'll update this review in a year or two. If it makes it to 3 year, I'd say it's a good value.

Pros:
* It can charge/discharge 4 batteries fully independently.
* It has 4 operating modes:
a) Charge - in this mode your batteries are fully charged using current that you specify (possible values are 200, 500, 700, 1000, 1500 and 1800 mAh for AA batteries and 200, 500 and 700 mAh for AAA batteries). Lower charging currents are supposedly better in terms of maximizing battery longevity, but requires significantly longer processing time. At the end of the charge, the capacity (in mAh) of each battery is displayed.
b) Discharge - in this mode batteries are first fully discharged followed automatically by the Charge function (a). This allegedly eliminates the memory effect, but it also increases the total processing time. Also not recommended to use this routinely, as batteries have a limited number of charge/discharge cycles.
c) Refresh - this mode is intended for older batteries or those that have been unused for some time. It consists of consecutive Discharge (b) operations. At the end of each iteration, the battery's capacity is compared with that in the previous iteration. The process stops when no increase in capacity is detected.

I've had several AA / AAA chargers over the years and even converted some hobby charger to test suspect batteries. Last decent charger I bought was a LaCrosse BC500 that lasted 1 year before the display went bad. After reading up on this charger that has been sold in Europe and the UK over the last year I decided to give it a shot as it had excellent reviews.

Very solid charger, well built and smart in design. Buttons and body are stout, and interface is well thought out. You dont need to select the cell like many chargers, controls work the last cell inserted. You can opt to put in all 4 cells and control all the same making charging setup quick. And yes, you can charge or discharge, test all together at different voltages by setting each cell then moving to the next.

Tested actual battery mah to 2 other chargers on 3 separate cells and it's very accurate to other readings. Heat sensor protection makes it safe to operate (haven't gone over 105F yet @ .7 amps). All in all this is a perfect charger for those that want all the info you could use to determine your cells are working well. Easy to use and looks built to last, much more so then any competitive priced chargers I've come across.

2/7/13 Update.
After buying a 2nd unit and running extensive testing along with some other users I've found some limitations that were unexpected. It seems at times it may false peak running full power 1.0amp x 4 cells. 2 other users reported this and it happened to me as well after many test runs. I've never had any issues running 4x .7amp charges and it's been 100% reliable at that setting (AA). So if your not set on running 4 cells at 1 amp and 3 hour or less charges are fine, it's still a very good charger for those condition.

Recommend .7amps for AA and .5amps for AAA. Stick with those settings and you should be good to go. Also, 1.0 and 1.5 amp charges should be fine for 2 cell charges in slots 1 and 4.
