Productbeschrijving
StreetSiren is een draadloos buitenalarmapparaat met een geluidsvolume tot 113 dB. Uitgerust met een helder LED-frame en een voorgeïnstalleerde batterij, kan StreetSiren snel worden geïnstalleerd, ingesteld en autonoom werken tot 5 jaar.
StreetSiren verbetert de efficiëntie van het beveiligingssysteem aanzienlijk. Met een grote waarschijnlijkheid is het luide alarmsignaal en de lichtindicatie voldoende om de aandacht van buren te trekken en indringers af te schrikken.
De sirene is van ver te zien en te horen door de krachtige zoemer en heldere LED. Wanneer het op de juiste manier is geïnstalleerd, is het moeilijk om de bediende sirene te demonteren en uit te schakelen: de behuizing is stevig, het metalen net beschermt de zoemer, de voeding is autonoom en de aan / uit-knop is vergrendeld tijdens het alarm.

As good or better than most.
Size: 4ft, Color: Silver
I was very happy with this item. It’s very heavy duty and appears to be something that will last me forever.

27" monitor mounted easily
Style: Single Arm, Size: 13"-34", Style: Single Arm, Size: 13"-34"
I ended up getting 2 of these monitor arms for the different desks in our office, and I am happy with both of them. The arms are super easy to assemble and adjust to the tension one desires. The arms hold the position where one sets them too, and the gas pistons make it super easy to use.
Each arm has a channel on the bottom that allows the wiring to be ran through and hidden, yet remaining accessible if needed. The mounting clamps hold securely and there is no wiggle whatsoever, and it is nice to have a strong feeling monitor mount.
It is lightweight and compact so it doesn't feel clunky on the desk. Highly adjustable left to right, up and down, and the screen forward and backward tilt. The price is really good for the overall value and quality of the product. Just make sure to order the right mounting arm depending on the size of your monitor, and you will be fine.
Nice quality and feel, and the aesthetics are great too.

Get this one!
Style: Dual Arms, Size: 13"-32", Style: Dual Arms, Size: 13"-32"
I got this dual monitor arm for my home office, and it’s been a total game changer. Having a dual monitor setup makes multitasking so much easier, especially for photo and video editing.
Setup was incredibly quick (under 5 minutes), and it feels very secure once mounted. I really like how stable it is and how easy it is to adjust the height and angle.
It also helped clear up a lot of desk space since I no longer need bulky monitor stands. Simple design, but it works perfectly. Highly recommend for both single and dual monitor setups. Great value for the price!

Pretty great product
Style: Dual Arms, Size: 17"-33"
Stand works great and as expected. I have a 32” monitor on one and a 26” ultra wide in the vertical position on the other.
I’ve had them for a few months and they’ve held tension perfectly. Usually, I find these spring tension arms to become loose after a few months and you just tighten them back up, these are still stiff like when I first set them up, and I move them around quite often. The monitors can rotate 360 degrees and tilt up and down almost 90 degrees each way.
The clamp is sturdy so you will feel comfortable making sure it’s tight on the desk. I do plan on drilling a hole to mount the desk to mount it without a clamp and will update my review when I do so. It comes with the hardware to do either mounting options.
They're made entirely of metal except for the plastic cable trays that clip along the bottom of the arms. The entire build is well worth the cost and gives me more space on my desk and helps my workflow when editing photos or editing video.

Pretty good product
Style: Single Arm, Size: 13"-34"
Assembly of the actual stand is easy, mounting to a monitor is not because of industrial design fluff. Gotta make the side you DON'T see look "sleek" and "smooth" and "organic" and "integrated" because...reasons. While this is on the manufacturer(s) of the monitor itself, what semi-modern monitor uses 100x100 VESA anyway?
The included long screws are too long. Even using the plastic spacers they'll bottom out with a 2mm gap; add washers and it's a lever arm and not solid or confidence-inspiring. I used a die grinder to remove the excess material closer to 75x75 and used the included short screws, perfect. So either include 25mm screws instead of the 30mm (but then the spacers would be too long), or just update the mount plate to 75x75 only, and throw 100x100 "compatibility" into the dustbin of history where absolutely no one will miss it.
Arm does move/adjust smoothly and is holding a 34" widescreen where I left it 2 days ago, so it IS a great product once it's properly fitted.
