Did a search here but didn’t see anything on this charger. Looks interesting, thought I’d ask you folks what your thoughts were on it. Kinda nice if ya have to charge a bunch of aa/aaa at one time.
Titanium Innovations MD-1600L
Titanium Smart Fast 16 Bay Ni-MH AA/AAA Battery Charger AC 100-240V + DC Adapters MD-1600L Today $52.85
Ill say what others have said - when this thing fails, youre out of luck, because its one charger with 16 slots, which means it might as well be your main/only NiMh charger if you have lots of batteries to charge at once, so you will still need a backup charger in case this one fails with all of its 16 slots or what not.
Id say, unless its proven to be super reliable, go for regular 4-slot chargers and charge with those.
My 2c.
ask HKJ opinion about this charger 
16 bay, I LIKE the way you think.
Not knowing anything about this charger, but it being a 16 bay charger I think it is safe to say that this was designed for PROFESSIONALS. How bad could it be? I would think that this is a no fooling around piece of equipment.
Before you buy anything from Rakuten, you should probably read about all the credit card fraud that seems to be linked to customers having used that site.
Beware…
I have ordered many times from Buy.com, never with a problem, but nothing since the buyout and name change to Rakuten.com. I never understood why they would change the name, Buy.com is a great name for an internet seller,
Probably so they can sell it.
An Amazon seller has it for about the same price, except Prime members get 2 day shipping.

The first review says it does 400mA, so it's not very fast, but not very slow either.
For $50, I'd be tempted. Charging my AA's already took a very long time before, and now all the Duraloops I'd added, it'd be nice to have a big charger like this. Sure I could use 4 smaller chargers, but then I'd need more power strips to make room for all those wall warts.
I just used that site for an example and hoping maybe someone would have something good or bad to say about it. I’ve seen it other places as well for slightly less $$, have read some reviews as well. Haven’t seen/read anything bad. These type chargers are mostly geared to pro photographers to charge their eneloops etc for their flashes. Might get one, not sure atm, thought I’d run by you folks 
Here’s one review I found…
I have a number of chargers, slow chargers, timed chargers, fast chargers, and very fast chargers (15 minutes). What I don’t have is a charger that will discharge and tell me the actual charged capacity of that cell. I am in the market for one. From what I can tell, this one will do the discharge, but not measure the capacity.
If this charger charges at 400ma, it probably will reduce the number of times a cell can be charged, by how much, I don’t know. I do know that professional photographers can not wait 8-10 hours for their camera batteries to charge, nor do I think that they would want to leave any charger over night charging, unattended. To them batteries are just a tool that helps them make money. Convenience is more important to them than squeezing the absolute maximum number of recharges out of a cell. A hobbiest, like many of us may very well get more satisfaction out of caring for their cells to the utmost.
Envelops can usually be had for about $2.00 each. Right now, at the Target clearance the “Duraloops” are about $1.00. If you take really good care of your cells, you may get 500 recharges. At $2 each that works out to about 4/10th of a cent per use! If on the other hand, if you abuse them, for instance use a fast charger and only get 100 charges the cost per use rises to 2 cents per use. Does this price increase matter? To some it would, others it would not. This charger is made for professionals, people who just want to get something done.
Up until now, I have been using fast chargers on my NiMH cells and I can attest to the fact that they reduce the lifetime of them. It is VERY evident with a 15 minute charger, less so with a 30 minute charger. I do know that I will not wait 8-10 hours to charge a NiMH. This charger here, someone mentioned, charges at 400ma per cell. This seems like a good compromise between a fast charger and a slow one.
A little off the subject of this charger, I ordered Monday and today, I received 2 of the MH-C9000 which can do this. Right now, I’m trying just a discharge of 3 aaa Duraloops. I think this is the quickest way to test mah capacity instead of doing the analyze function which I think takes a day and a half. Something else I found while reading their FAQ you might like. I don’t know how correct this is. I have also read **loops can withstand a little more with degradation.
