Yes, just ask for it back. I was burned back in 7th grade I lent one of my video tapes to a friend and never got it back. And I have never lent anything ever again.
Remember you paid good money for that item, you shouldn't let someone rip you off. Simply ask for it back and be persistant about it. It's yours, you lent it to them to try, not as a gift to keep forever.
And yes there are people who do this all the time, could I borrow this? And they never return it, and they even forget they have it. Oh no I gave it back to you months ago. Some people get a thrill out of it. Like shop lifters do. And it's like shop lifting. Your taking something that you didn't pay for.
I had a neighbor a long time ago, who was a lifter, would borrow whatever she could and then swear up and down she gave it back to you, even if she was standing there with it in her hand. She would tell you, I gave you, your's back. this was the one I bought. Everyone in the apartment complex, hated her for this, as she had managed to get people to lent her this or that, half her apartment was someone elses, stuff. When she couldn't pay her rent, the manager open the door, and said if you can prove anything here is yours, get it, the rest I'm putting on the curb. She lost about everything she owned that day, I'm not sure if everything she had was someone else's or a few people decided to pay her back. But there was only a bed, and about five boxes worth of stuff on the curb waiting for her to either pick it up, or the trash man to toss it.
