Input:
Question: Where is the battery compartment and what size batteries do you use. There were no instructions with this remote control.
Document: Put batteries in and use it. Vizio should have came with this. Only problem, is blue buttons are hard to read in low light.
I bought this remote to add a QWERTY keyboard to my new Vizio 50&#34; LED tv. It works exactly as described - simply add batteries and use it! The keys are a bit stiff (may soften over time), but having the keyboard is such a blessing, compared to trying to navigate the on-screen keyboard. Makes YouTube, Netflix, and Facebook 1000 times easier!I highly recommend this purchase.Delivery was prompt, well packaged, and free from defects. Good job!
You really need this remote to fully use the apps on the TV. The signal strength isn't amazing for me, but my TV is accross the room. Overall It's good.
I bought this remote since the one that comes with the TV do not have the qwerty keyboard, therefore it will be more difficult to use FB or any app.Recommended for all those like me who likes to use youtube and do not want to spend time browsing thru the letters with the regular remote.
Cool. This remite control was amazing although I had to update the firmware on my TV so it could work.
I don't particularly like having to pay for a remote, but this is worth every penny. Having a working keyboard when navigating with a smart tv makes the entire viewing process better. Passwords and searches are significantly easier. The only nit is that this doesn't come with any instructions, but with a lot of things, you find out what you need to.
Received this today and had to write a review! The original remote that came with my Vizio TV is very cumbersome and takes forever to type your email address, passwords, etc. in to navigate around the various sites (it's a Vizio 55&#34; Smart TV). When I opened this up, put the batteries in and tried it out...WOW! What a difference. I absolutely LOVE IT!
i have a vizio 3d tv (47 in) and after a year my remote died. i bought this remote and when i received it,  i put in the batteries and it worked instantly! Thank You so much! I did try to call vizio and they recommended i buy a 30 dollar remote that was different from the one that came with the t.v.... i was disappointed with the advice so i researched on the net and found this. Best choice and saved some money!
Had difficultly finding how to put in the batteries and how to even get it to work. But now it works fine.
was almost impossible to open to put batteries in. Even my handyman could not open it. Luckily I had another one from another Vizio TV so I saew how it opened,
