A little deeper than a standard GCFI outlet
I installed this in a 2-gang box as the load off of a standard CFGI outlet in a bathroom. The height and width were roughly the same as the CFGI outlet, but it’s about 1/2″ deeper. That left a little less room for the wiring but it was fine. Works great.

Reliable and Great value
I bought the same outlet years ago and purchased it again when I got a new house. Very reliable and cost-effective.

Works well
Instead of using transformers for charging phones I installed them all over the house. If you plan on doing it yourself. Look in the breaker box and make sure you buy the right amps for the circuit. We had 15 amp all over my condo built in 2000 but there was 20 amp in kitchen, because of the appliances. If you have an older house the back boxes may not be big enough to support the size of the USB receptical back part. Larger than normal. They may make smaller backs now or in the future? I tried to install in my nieces house built in 1970 but could only install one in a part that was remodeled. All the other receptacle boxes were metal and small. Even smaller when wires are looped through them. Maybe TMI?, but it pays to think things through before you hire a handyman or electrician.

Not UL certified
Leviton is a good product. This went in very easily and is working fine so far. The issue I have is that this product is listed as UL Certified yet I canât find the UL mark anywhere. Not on the outlet, the packaging or in the paperwork. I donât care about offshore certifications that are âequivalentâ, I want UL.

wrong item shipped but the actual Leviton USB outlets are great
I know the actual Leviton T5632 outlets are 5 stars but I ordered Leviton T5632-BW (http://www.amazon.com/gp/product/B002DQT22G?redirect=true&ref_=oss_product) and got Part Number: M22-T5320-WMP Receptacl 15a Tampr 10pk Wh (http://www.amazon.com/Receptacl-15a-Tampr-10pk-Pack/dp/B00R02GC4O/ref=sr_1_2?ie=UTF8&qid=1456676788&sr=8-2&keywords=leviton+t5320-wmp)I realize now why the star rated only 1 and that is because prior errors for other customers were the same as mine.Be careful what you order you may not get what you want.

I bought two receptacles, one for the kitchen and the other one for the bedside table. I’ve been using the one in the kitchen for two weeks and like the clean look compared to a large 5 device charging station. I haven’t installed the second receptacle to date. Product is made in China.
