i would like to first start with saying that since i got my first Lovense product i have been more then happy with them and so have the lucky someone/s that have had the pleasure to join the fun.
in saying this i do have a few complaints about the products.

Max 2...
first to be added to the collection was the Max 2 for my own personal use, before buying it i should have checked out the size specifications as to how much of my dick will fit into it. its great for those who have an average or small one. but for myself i am 9 inches without a cock ring, well you are going to be lucky if fit 3/4 into the thing.
and Lovense is no help at all with the way they describe the dimensions from the front page of where you buy the max 2, it shows a diagram image with dimensions stating 9.50 inch in length and 3.33 inch in diameter (that is not the inserting, its the outside casing).
so in order to find the true dimensions, you need to go into the FAG section that is another page and find the following that is basically a heartless note left by Lovense to let you know that you have wasted you cash if you have a big dick.

1. What is the insertable size of Max 2?
Max 2 is about 6.5 inches deep. If you are longer than this, you shouldn’t worry. The most sensitive parts are toward the beginning of the penis.

5. What if I am too big/small to fit into Max 2?
Max 2 is designed to accommodate around 95% of men. Guys up to around 14.5cm in girth should be able to comfortably enjoy it. The air pump design ensures all men feel the sensations, which mimic vaginal contractions. If you properly apply lube on your penis, on the entry hole and inside the sleeve even above average sized penises can use it!


so as it says here, yes it feels good on the end of your dick. but i am sure that everyone can agree that when your thrusting in, it does not feel good to be smashing your knob against a hard surface. unless your into that kind of orgasm denial thing...
as for the air pump inside of it, it feels great if your just letting your dick stay in without moving (or very little movement) that is until it squeezes so tight that it pushes your dick out and you can not get it back in without waiting a couple seconds for the pressure release.
i do not know about anyone else, though when i am in the heat of the moment and close to cumming and my hips start moving, the worst feeling is when it pops out and you go to thrust in one last time and its slips n your suddenly blowing all over what ever is in front of you and the outside of the Max 2. as you can imagine this not only does not feel as good as it could have if was inside the thing, but also end up with a mess to clean up...

so i will end with saying.
the Max 2 is great if you have a dick that is smaller then 6.5 inches...
or if you have a larger member, then you are not going to have such a good time. be prepared for always being left with close to half your dick not fitting, a bit of pain and a lot of mess...
