Good enough for 300' up.

They are matching colors for the business I work for. I climb towers. These are great. They are snug enough on your face that they won't blow off in the wind but so comfortable you can wear them all day without notice. Great product! 5 stars all day.

It's great up up to 300 yards but I have to check readings several times to get the distance perfect.

Replaced an old 150W metal halide wallpack, 22' up. Beam pattern better and brighter then similar adjacent M/H wallpack. Construction is good.

This tv stand fulfilled my need to have a taller than average tv stand. It's fairly sturdy and has plenty of room on each shelf. The plastic doors are a little ghetto, but they do serve their purpose and i don't think they'll break or come unseated. I have a 50 inch 4k TV that weighs less than 40 pounds. The TV's weight causes a slight sag in the middle, but it isn't very noticeable and I'm not really worried that it won't hold.

This product is very sturdy.  I have 300 plus pounds on it with no problem.  Also, it is stable when weights are not balanced.

Pulls 28" or vacuum in a couple of minutes on a 7lb system. Good enough for the field.

Sturdy enough for the price, moderately easy to adjust the height.  Locks shut after collapsing, and it has a lock underneath to keep the center from going anywhere.  Easy to move around.  I pair mine with a stretchable, fitted tablecloth at max height of 3' when I DJ friends' parties, and it works great as a surface.  It's currently my TV table in my bachelor pad, which looks great with that tablecloth on it, IMO.

It doesn't reach 300 feet. It blanked out at 50 feet.

Works well but for our house we didn't get near the 300 Ft range it says, even after moving around the receiver a bunch.

I've used it a few times now. Good quality, steel legs, and tall. I'm 6'3" and can walk under it on it's 3rd tallest setting. It would be a 5 star review, but minus 2 for shipping the wrong color (but plus one for how they handled it). I will probably buy again for the white one

It has decent volume and sound quality. The control range is slightly better than the 30ft advertised. The microUSB charger fits VERY tightly, but it holds a charge very well. I've played it for 10 hrs continuously without it dying. I haven't tested its waterproof qualities and don't really plan to. I mostly got it for camping or having at work on weekends, and so far I'm pretty happy.

Once assembled, the unit supports weight well on both sides (for pull ups and bar dips) without any tipping or rocking. Bought this during the holiday season on a "daily special" for about $175, a good value, probably even worth the current $212 price. Two reasons for the 4 stars rather than 5:
1) The unit is about 7-ft tall. It would be nice if the unit's pull up bar was adjustable because with a standard 8-ft ceiling, your head quickly approaches the ceiling.
2) During assembly, some of the bolts required running the nuts up and down a couple times to clear the threads. When tightening them, I found some of the connection points beginning to compress the square tubing a bit. Without any warning about this in the instructions, I suspect the unit may come from China with some slightly poorer steel.
Yes, I would still recommend this unit.

Ordered 300 ft. of this cable and it worked like a charm. The terminals are not crimped on which makes these cables more appropriate to be used inside.

Works to 360 yards. Never tried to range a two story barn on open ocean but id bet it would reach 600 then. But hey, its pretty accurate to 300 and gets even a person at that range. Id buy again at the price but was a little disappointed.

For the price I was only expecting a toy but it is a little better than that.  300 foot range is a bit much unless you are in a large very quite building !!
quick delivery and packaged well !

So far, this proves to be a good extension lens for my 300mm telephoto lens. It feels solid and well built for the $$. I have not used it enough to really give it a 5 star rating. I will be able to report more during the spring and summer months. As of now, it's cold here in Mich...and I'm not as active with my photography. Maybe I'll take a trip to the skiing lounge to really test it out. However, with this lens attached to the camera body, you will need to switch your lenses to manual focus. If you're not use to that, I would hold off purchasing this item until you are more comfortable.

This is excellent for the price. My main problems are that there is really no way to level it, so make absolutely certain your floor is sufficiently level. Despite that, I have had 300lbs (136kg) loaded on the bar catches with no warping, I have yet to drop the weight on the safety bars but they seem fairly strong and have supported at least 250lbs (113.4kgs) resting stationary on them. The chin up bar is nice and sturdy and supported me at 240lbs (108.9kgs) without having to be anchored to the ground, although I do have to bend my knees in order to fully lower myself at 6ft (1.83m).
