There are now 4 different sizes of Hush plugs: 1", 1.5", 1.75", & 2.25"... The 1" & 2.25" plugs are only available in the Hush 2 version which has been out since at least the beginning of the year in those sizes. The 1.5" & 1.75" sizes were the small & large of the original Hush release.

The original Hush had some major issues that make it so that you should never buy one (unless you can get it super cheap). I went through 2 of them, Mistress Ayn had 2 or 3 fail and she has reported (in some cases on here) about other subs of hers having gone through 2 or 3 devices. Basically, after about a year, the original device either stopped recharging or the vibrator died.

The other major issue was with the bluetooth connectivity as it was almost impossible to keep the connection unless your phone was several feet away from you (this is because it radiates as a ever growing cone, which meant it was huge at 15 feet but really small right at your body).

For the Hush 2 the bluetooth connectivity is much better (but still not the greatest) and they have changed the charging method. On the original Hush it was a cord you inserted into the device itself, whereas the Hush 2 is magnetic on the outside of the device. I suspect that the charging problem of the original had a lot to do with the mechanics of the port being shaken loose from the intense vibrations, so the change in this MAY fix this issue as well.

However, because it usually took about a year for that issue to show itself in the Hush, and the Hush 2 hasn't been out that long, it has yet to be field tested enough to know for sure. The other "issue" with the Hush 2 (and honestly all of the magnetic charged Lovense devices) is that the indicator for full charge and for not actually having a good connection to charge are exactly the same (which is to say no light). When it is charging, the light at the base of the Hush is on. When it isn't (like when it is fully charged), the light is off. So, you may think you have charged the device when in fact you haven't (both of my subs have had this issue at times). You can check charging levels of the device by turning it on and connecting it to the app if you are unsure when you are done however.

As for the plug itself, it is really high quality and design. It uses medical grade silicone and fits better (and more comfortably) than any plug I have ever worn (vibrating or not). I have always gotten the 1.5" and have actually been made to wear it constantly for up to 4 days straight by a Domme. Every other plug I have ever worn has fallen/shot out of me at a certain point, but that has never happened in all the times I have worn the original Hush. I have also had the 1.75" put inside me by a Domme and that also had no problem staying in, although it was a little painful for me and thus not as comfortable.

Just last week in pre-session anticipatory activity with a Domme, I was told to put in the Hush 2. After about an hour, the Domme started doing live control and sent me intense continuous signals which lasted for a full two hours before the charge ran out so that should give you some idea about how much you can play on a single charge with the new device. However, if instead of playing continuously you are randomly sending patterns or taking control for 5 minutes at a time then the charge will last several days without recharging.

The vibrations on all the Hush devices is intensely wonderful and is easily controlled. The app is also great for use both locally (from the connected phone/tablet/computer) or remotely (remote app sends signals to locally connected phone/tablet/computer). It is not specific to the Hush but actually allows you to control any Lovense device from a single console (including, in some cases, multiple devices in/on the same sub).

Through the app there are also group modes where one person can send signals to everyone else in the group (so a Domme can send the same patterns or live instructions to many subs at once). There are also the Lovense special events which last 24 hours and are controlled by people posting hashtags to Twitter, which then controls all devices logged into the event around the world based on how many hashtags it receives (this is very intense).

The other major ass play option besides the Hush plugs are the Edge devices. This is not specifically a plug, but rather more focused on intense prostate and perineum massage. It is made of the same medical grade silicone but has two vibrators in the device rather than one. I find this device to be a lot more intense when in use but overall much less comfortable. Also, unlike the Hush, I have had this fall out of me both of the times I have tried to wear it under my clothes while out in public.

So my advice is to get the Edge for dungeon or remote session play but go with the Hush for public play or when you want to be able to mess with the sub over a period of time to remind them of who is in charge.
