This little egg is good if you like eggs but is a bit different if you're used to thin vibrators like a bullet or something similar. It's strong and is waterproof so you're not confined to the bed. If you're not alone in the house a TV or computer playing something will help drown out the sound, but it is well worth it for being so cheap.

The egg is made out of plastic but it has a velvet coating, making it nice and smooth. I've seen in some reviews that it has a plastic-y smell but mine really didn't have any smell at all... But I wash all my toys as soon as I get them out of package so that might have had something to do with it.
The wire is made out of a surprisingly strong, stiff material and is anchored to the little button and the egg really well. I've accidentally dropped it a few times and grabbed it by the wire and it is still strong and waterproof.
The texture is obviously very smooth, even the waterproof ring on the egg is surprisingly smooth and unnoticeable.

The button on the One Touch Wonder is unique and well anchored to the wire and has little ridges on it for extra grip. Though when you hold it, it is a bit awkward since it is relatively small.
The little LED light that shows the vibration on the bottom of the egg near the wire is neat, though not extremely necessary.
Since the egg is plastic I would not use silicone based lube. I've used silicone lube on plastic toys before and it had a bad result.

For me the last function of the toy was a bit meh and really didn't do much in the pleasure range.
As it says this toy is waterproof and the wires are pretty sealed up as well, making it a fun little toy in the bath or shower.
Before I was able to buy toys online I used a vibrating tooth brush, and surprisingly the tooth brush is better than this egg when it comes to vibration. It is strong but it is more for area pleasure and not pinpoint pleasure.
The batteries are strange on this thing... I've never seen a battery like this before and the warning on the battery was a bit scary and will probably be hard to replace locally.
For such a cheap toy the One Touch Wonder is pretty moderate in sound, only a bit louder than an oral B vibrating toothbrush.

Being waterproof, the toy is easy to clean: just use a toy wipe or wash with some antibacterial soap. But at the base of the toy where the wire is you have to separate the wires to get in between them, same with the little button.
