5Good Item
By T. Yamazaki
I use it for my Japanese home bakery machine, almost everyday.The bakery machine only requires 350W, but I bought 1000W transformer, so it has enough power for the machine sometimes runs over 8hrs, depending on what kind of bread you make.The transformer is very easy to use, infact, the instruction is just a couple of sentences long. I have been using it for a month now, everyday, no problem. No heat is created, too.Good thing is that I can always take this back to Japan to be used with American appliances.It was a bit difficult to plug in the appliance at first. I don't know if it's just me, but I really had to push it in.Good Item, very reliable, highly recommend!

4Works as expected
By Paul
Pretty good! Works as advertised. The 100V plug seems a little odd but *does* fit our rice cooker; it took a bit of pushing though at first. It's getting easier now.Reasons for 4 instead of 5 stars:- The 100V plug *is* somewhat odd (although it does work)- Instructions for switching the fuse were not included with the unit. There was no paper in the box, nor was it printed on the box as support suggested. However, support did explain by e-mail about how to do this.Please be aware that the voltage "switch" is just for the input voltage. Do not plug your Japanese appliances into the 117V plug; only the plug on the right is intended for this and the voltages are different.

5Must-have for Japanese & other 100VAC Electronics
By D. Chan
If you have electronics which require 100VAC input, this is a must have. Don't listen to your friends who tell you the 120VAC outlet works just fine. It's not true. I had other Japanese domestic electronics which used on the 120VAC outlet. Yes, they worked for some time (like a year) and then died. I know it should have lasted for longer than a year if I used it at 100VAC source. 20% Overvoltage and constantly stressing your equipment is NOT a smart idea, especially if you are running expensive gadgets.Anyway, I got one of these from this seller is because either the local stores mark up the price (I got quoted $85 + tax!) or the online stores charge high S&H (the 1kW step-down transformer weights about 20lbs!). So I found this seller. They sell at a discount already. PLUS, the S&H is only $7. The sub-total is much lower than what the next cheapest seller would charge. Packing is good. It's basically 100% the same packaging from manufacturer.This unit is Made In China, but rest assure that you'll get quality product. The manufacturer is a good one, and the transformer is tested to be reliable AND stable.Recommended!!
