5X Periscope HD Monocular Portable Monoculars Periscope, Adjustable 20" to 27" Observation Telescope for Bird Watching Hunting Hiking Concert Travelling

I bought it to be able to watch my two high schoolers bowl at crowded tournaments. Since most bowling alleys are typically not set up to favor the spectators, this periscope has allowed me to see shots when the players and coaches are all standing in front of the lanes. It is sturdy, came with a nice case, is simple to use, and works just like I expected. It isn't bulky to haul around nor is it really delicate that I worry about using it. Lastly, the list of uses on the package of this periscope made me laugh since I just pictured some random person running around looking around corners, which then creeped me out a bit. 😂 (See photo above for entertainment). I have already recommended it to other bowling parents, struggling to see their children's shots.

I supposes you get what you pay for. I personally find this thing to be mostly useless. The field of view is awful, the adjustment knob on the ocular lens doesn’t really do much of anything. It’s a novelty, it isn’t in any way good optical equipment. Again, you get what you pay for. The marketing hype for this thing simply doesn’t deliver in real life use.

It's good overall and I can adjust my eye relief just fine. Works in bright and low light levels. The only issue I have is the silver aluminum piece from the photo popped out from somewhere on the extender I believe. I just got it the day before. Everything still works except I think it might of been a break cause instead of the being a few mm gap when the arm is completely lowered, there's no gap now and it'll slam into the top of the monocular. So over time I worry it might crack the glass. It should be an easy fix but I haven't for the life of me figured out where it popped out of.

This thing is pretty cool. I like to watch what my dog does when he first gets to daycare but the fence is high. Now I can see right over it, clear as can be.

I was really determined to love this periscope when I ordered it, despite having read that it gets returned frequently. On the plus side, it seems nicely made, and the mechanism which extends the length is nice & smooth, and it comes with an attractive looking case as well. HOWEVER and most importantly, no matter what I did (changing the distance, the angle, the height of items I tried looking at, etc.), there was zero focus even though there is a "focus" on it. I never once could really see anything, and I tried it many different times before making the decision to return it.

This periscope is awesome. We go to tons of Bowling events and the college teams stand the whole time that they are playing. With the periscope we can see each throw. It is so cool.

The eye piece doesn't swivel. But it's ok
