Lower end dashcam
I purchased 1 of these about 1 1/2 yrs ago from Sears and it still works but initially the problem with that unit right from the start was the manufacturer included SD card did not work. As soon as I used the SD card from my Nikon digital camera the unit worked. I have since purchased a few extra SD cards from Staples and they all work fine in the unit. The other problem I had with the one purchased in Sears was the flip lever/suction cup mount system lasted about 1 yr. and the broke. When you mount these you flip a lever to pull the plastic suction cup creating suction which holds it to the windshield. Well, the plastic suction cup on the one from Sears seemed way too stiff where there wasn't much flexibility so when flipping the lever it takes great force to activate suction. In short this great force breaks the plastic flip lever shaft that connects to the extremely stiff plastic suction cup. Being the dash cam itself works well I bought this one from E-bay being the price was low enough. Sure enough the SD card did not work but as soon as I put in an SD card from my digital camera or one from Staples the unit works. Once again this unit has a stiff plastic suction cup which with this unit is so stiff I can tell if I flip the lever all the way it's going to break the plastic shaft that connects the flip lever to the stiff suction cup. As for the seller it was curious that the box did in fact look factory sealed BUT inside the manufacture SD card was just laying inside the box not in the little plastic bag it is shipped in, which was actually in the box too. Another issue was the battery which is always installed in the unit was in the box not in the dash cam and it too was just laying in the box. My conclusion is the unit was in fact previously opened.

TV antenna
3 von 5 finden das hilfreich I live in NY State with Albany being about 60 miles and NYC being about 90 miles away. What I learned in the past was using old rabbit ears made decades ago before HD broadcast even existed worked at getting digital broadcast. In fact I could get the Albany stations 60 miles away. I am not able to get NY City stations. Then wanting to hook an antenna up to another TV in my bedroom but not having an antenna I found just a plain coax doesn't work. So I tried splicing into the coax one of those loop AM radio antennas you get with stereos and sure enough even that worked at getting the same stations 60 miles away. I figure though if I could get rabbit ears at a great price I'd grab them. Sure enough this unit purchased on E-bay was a great price. I ordered it on Aug. 14, 2017 and received it on Sept. 8, 2017 which isn't the quickest delivery time but much less than the promised by date of Oct. 13, 2017. Unlike most things I've purchased on E-bay this thing was amazingly packed well for shipping. Not only did they have a small foam piece against the unit to stabilize it but it was wrapped in bubble wrap and then placed in a bubble insulated envelope. The coax connector you connect to the TV is a tad clumsy but no big deal being it's not going to be often that you have to connect it to a TV. The unit is a tad light. It stands well on it's own but the weight of the coax hanging can pull the unit enough to make it move but once again it's nothing to even be concerned about. As for it working what I do know is it works well enough for me to get those stations in Albany 60 miles away. Please keep in mind though that I've noticed both weather and line of sight will affect what stations you get. On rare occasions I have to move the antennas to get the signal or will lose it completely regardless of where I move it. That's where one of those on the roof antennas would probably work better. Anyone in a city where they have stations will most likely get those stations no matter what the weather or your line of sight is. I'll continue to use those old rabbit ears of mine for the main living room TV being they work. This pair is for my mom's kitchen TV just so she can have a some stations even though she has cable. With Spectrum (Time Warner) you can't run extensions to connect other TV's unless you pay $4/month for 1 of their converter boxes. They already get enough of her money. After writing this review I'll be ordering a second unit from E-bay (the same seller) to replace the AM loop antenna I have spliced to a coax in my bedroom.

A solid and affordable pump that seems to work well.
1 von 1 finden das hilfreich Having never used one of these high pressure pumps previously, because of the very high pressure involved, I used it with extreme caution.
As soon as I opened the box I felt this pump seemed factory fresh and rather solid. Then, it's a matter of reading the user instructions which, I might add, are basically a joke however, the pics. and diagrams can be useful. Once removed from the box, all one really needs to do is attach the pressure gauge (ABSOLUTELY use the tool included) and pressure hose (same tool) and handle (2 simple screws with hex tool included). There is no need to use sealing tape/putty or anything like that on any threads. The factory gaskets/o-rings do the job when the threaded portions are snugged.
Those not familiar with tool use will often over tighten things. Do not do that particularly with threaded brass, as the parts in this pump are. Brass is common where corrosion is a concern. You will snap the threads right off. Make them snug BUT not totally as tight as possible. When installing brass fittings it should be possible to tighten them beyond (even though you won't) the tightness you end up leaving them at. At worse, if they are not snug enough and leak a little when pumping, you can always snug them up a little more.
I also suggest snugging up both large tube nuts (one at the base of the tube and goes into the junction block and one at the top of the tube just below the handle), the pressure bleed valve and air output adapter. Before snugging up all threaded portions I actually removed the ones the factory installed in the junction block just to make sure the seating gaskets/o-rings were in place.
Once everything is snugged up, you are basically ready to pump. The pump hose from the box fit the fill adapter (port) on my gun. I suggest putting on safety glasses when using this pump because at 2000-3000 psi for most guns if there is a part failure the extreme pressure would be like a mini explosion. The first few pumps nothing seemed to happen although there was no hissing sound from leaks. Perhaps it was just "priming" up. Then pumping pressure began. Pumping the pump was very smooth. Curiously, for the first 30-40 pumps, lifting the handle required as much force and pushing it down, which isn't a lot.
My 22 cal. Benjamin Marauder rifle had 1500psi in it as per the gauge on the gun. To get to 2900psi (3000psi is the max but I like being safe to give the gauge a little error room) it took me about 110 pumps. Even though I'm rather lean and light, I do work out regularly and found it was rather easy to do the 110 pumps. I will say though, once my gun reached around 2200psi the pump resistance increased as the pressure increased. In fact, I'm impressed the pump actually keeps a seal with such force on it. The last 10 to 15 pumps I almost had to lift my feet to let my weight force the handle down.
Please note: During the first 20 or so pumps, my pump gauge stayed on zero and then jumped to 1000 psi.even though my gun gauge read 1500psi. As I filled my gun, the pump gauge always stayed 500psi behind the gun gauge. As far as I was concerned, I relied on my gun gauge to track the pressure, just as I do when I need to know what level it's at and when it needs to be refilled. Basically, unless the pump gauge just needs to prime up and in time will work, the pump gauge is useless and I recommend using your gun gauge. If the device you are pumping up doesn't have a gauge, use a reliable pressure gauge to monitor the pressure and determine the accuracy of the pump gauge. I'm not even sure I want to file a claim with the seller or Vevor being I plan on watching my gun gauge anyway, to determine the pressure inside. For me I'm thinking they could have just given me a brass plug to thread into the gauge port in the junction block and saved money on the gauge (which I've seen selling for around $20 new) and made the pump price even less expensive.
Finally, after reaching your desired pressure, DO NOT try to remove the hose from your device or the pump without first releasing the pressure inside the hose. This can be done by a simple slow turn of the pressure drain valve (in the junction block) until you hear hissing and let the hose and pump junction block pressure drop to zero. In my case, even though the pump gauge didn't follow the gun gauge, it still registered pressure and dropped to zero once I bled the pressure from the hose and junction block.
You will get some spare gaskets/o-rings which could be useful down the road. They also recommend re-oiling certain pump components which are designated in the instructions. You will need to obtain the proper oil which, at this time, I do not know what it is. I figure the factory specified oil MUST be used.
In conclusion, for the price you can't go wrong. Why spend $200 plus when this pumps works. As for how long I do not know but do know if it lasts for even 20 fills (comes out to $2 per fill) I'd say I got my money's worth.
