  • Upgrade Description:
    [Charger]
    Enhanced Safety: Multiple intelligent protection systems have been added, including overcharge protection (automatically shuts off when fully charged), overtemperature protection (suspends charging when the temperature is abnormal), short-circuit protection, and reverse polarity protection, significantly reducing safety hazards during charging.
    Durability Improvement: The outer shell is made of high-temperature-resistant, flame-retardant ABS material, offering improved drop and scratch resistance. The charging port is gold-plated to reduce oxidation during insertion and removal, ensuring a more stable connection and extending the overall lifespan of the charger.
    [Battery]
    Overcharge protection (automatically shuts off when the voltage exceeds the threshold) and over-discharge protection (triggers a low-battery warning when the charge level drops below 20%).
    Physical Protection Improvement: The outer shell is made of a flame-retardant ABS+PC composite material, with temperature resistance increased to over 120°C and drop resistance increased by 50%. Insulating thermally conductive gel is filled between the battery cells to prevent short circuits and accelerate heat dissipation, preventing thermal runaway caused by high-temperature accumulation.
    Extended service life and increased cycle count.

    [Upgraded Front Axle and Screws]
    Improved corrosion resistance prevents rust and seizure even in rainy and muddy conditions, ensuring smooth disassembly and maintenance. High-strength standards withstand greater radial impact forces (such as the transient stress of sudden braking and bumpy roads), reducing the risk of front wheel loosening due to screw deformation and breakage, and fundamentally ensuring structural stability during riding.

    Utilizing a precision thread rolling process, the thread profile is more uniform, improving fit with the front wheel hub and frame connection holes by 30%, making it less susceptible to loosening due to vibration after installation.

    Two new stainless steel wrenches enhance maintenance convenience and adaptability.

    Specialized adaptability: The two wrenches correspond to the external hexagonal size of the screws, eliminating the need for users to search for additional tools. Whether performing daily inspections, changing tires, or adjusting the front wheel position, these tools are quick and easy to use, making them particularly suitable for non-professional users.

    Upgraded durability: The wrenches are made of one-piece stainless steel with a hardness of HRC35-40. They are more resistant to bending and wear than ordinary carbon steel wrenches, resisting deformation and rusting over time. They can be used with the vehicle for extended periods, eliminating maintenance interruptions caused by tool damage.

Attractive
Size: 4 Panel-88'', Color: Grey
The assembled product is just as described. The screens look great! I am using them to hide the cluttered shelving in my garage. The area now looks quite neat Something I must say, though, is that the assembly was extremely difficult. I had to use a silicone spray and some pounding to get the A and B poles to fit together. Also, it required a great deal of strength to stretch and hold the fabric panels so that the bars inserted in each hem lines up with the screws inserted in A/B poles. I strongly recommend having a partner to help with the assembly. while sc and screw into poles them once inserted intetchedtne end of each pole ( and B poles barely fit together. I used silicone spray on the end and then pounded them

Does the job, but assembling by yourself is a nightmare
Size: 4 Panel-88'', Color: Black
Does it do the job? Yes, although as others said there are small gaps but it's not a huge deal. The price is also good. But the reason I'm giving it a 3/5 is simply because the assembly for this was a complete nightmare. I honestly don't think I would recommend this to anyone unless they have another person to help them assemble it, because doing it by myself was terrible. I don't think I'd buy this again, I think I'd opt to just spend a bit more money and save myself the trouble personally.

Reasonably adequate room divider
Size: 4 Panel-88'', Color: Beige
I'm reviewing this as I assemble it. Couple things: 1. I didn't expect as much assembly. I've ordered dividers before and they more-or-less came as one unit. Sometimes the panels needed screwing together. These require complete assembly and come largely as three rods: two make up vertical columns and snap together. Another one (called part "C") makes the horizontal columns and you have two of these per panel (one attaches to part "A" and the other part "B"). These parts are metal with a plastic shim. Using the wood screws to attach to part "C" is a real pain in the neck. There's not much holding the panel in place so it's a little tricky. One tactic I've found while I'm assembling that works for the initial connections from parts A and B to their respective "C" rods is to hold the screw in place with a screw driver and then rotating the rod around the screw. This will do a number on your hands if you aren't wearing gloves. This obviously doesn't work when completing the connection. Using a driller driver on this is really near impossible because there isn't anything you can use to secure it in place. You can use it on the first panel, but as it gets longer, it becomes increasingly difficult and because it isn't wood, it's really tight. I considered drilling larger pilot holes but since there are only 4x4=16 screws I need to screw in, I just decided to use my screw driver to complete it. 2. Also related to assembly. When completing the panels (attaching parts "A" and "B" to parts "C" that have the cloth cover on it), you have to be careful that when you tighten that side that it isn't loosening the other side. Because the pilot holes are so tight, you can end up rotating the rod, which rotates it in the same direction as looser on the original side. Having someone hold the "C" rod in place while you screw it in is probably the easiest approach. I didn't have a 2nd person, so I just had to keep flipping back and forth and tightening both sides as I screwed it in. Not the worlds biggest deal, but annoying nonetheless. 3. The way the instructions are written, they seem to suggest building this thing progressively; that is, you do panel 1, then 2, connect them together, then do 3 and connect it, etc. I took a different route that I suspect saved me quite a bit of trouble, and I assembled all four panels first and THEN connected everything together. 4. For the love of God make sure you check that the plastic tip is on the same side for every panel. Otherwise, you have to take one side apart again and reverse it. On the bright side, if this happens, you've essentially bored out the pilot holes to be the correct size... which is having me question if I shouldn't have just bored them out to the appropriate width in the first place. 5. Attaching all of the panels together is also an enormous pain in the ass unless you happen to have an 88" long elevated surface. Attaching the legs either requires you to elevate one side, which will invariably twist the inexplicably cheap material in the bottom connectors... or you can attach them sideways... or you can put this thing upright, having two people hold the panels in place while you use the allen wrench to tighten the bolts on the underside. None of those are particularly great options. NOW on to the utility itself. 1. The panels do let some light through (I didn't believe their advertising, and that was one of the reasons that I bought beige, is that I wanted it to not be too dark). They aren't transparent though, so it isn't that far off from their description. They functionally work great, and keep the mess of wires hidden and when I'm sitting at my desk, actually reflect quite a bit of light into my office. Great! 2. My wife has described these as "the most hideous piece of furniture ever conceived of by man." So it does not have spouse approval factor. Granted, she will seldom be in my office area, so that isn't the end of the world. 3. These are really hard to align in a way that doesn't look a little tacky. There are some plastic connectors but they don't do a bang up job of keeping these in place. Each panel is slightly tilted and it's... quite obvious. I may at some point make my own improvements to these to help make them more level. It's not a particularly expensive product so I wasn't expecting much so it's fine and I'm not going to ding them on the rating because of it. All said, would I buy this product again? Probably not. It's assembly was ~90 minutes which is about 75 minutes longer than I was anticipating spending on this (not including the 5 minute writeup that I'm doing here). But am I going to return it? Also no, if for no other reason I'd be just as annoyed taking it apart and putting it in the original box to return it.
