These 3D DLP-Link glasses are pretty comfortable, even when wearing normal glasses. They fit perfectly, they are light in weight, and the battery is long-lasting. I have watched several movies and haven't had to charge them yet. They darken the image a little, but it's hardly noticeable. They take half a second to synchronize, and even if you move your head, they stay in perfect sync. When I bought them, I didn't think they would work so well. They're just perfect for me. In fact, I have two pairs!
It does not have much power (light power), which is the only downside. The rest is great, it works with my power bank, USB input, micro SD card, mini USB (compatible Android otg), HDMI and video. It is super compact, smaller than an adult hand, and I use it to watch movies from the laptop projected on the wall. It does its job perfectly. It is so tiny and lightweight that you can take it with you everywhere. I recommend it, I'm in love with my little projector.
I'm really happy with the product, it works perfectly with Ethernet and USB interface. The printer is very fast and offers a strong beeping sound that can be set to ON-OFF. It didn't take me long to install it, but it's true that I'm in the IT business. Maybe a basic user needs some help. I use it with an Android tablet and the Loyverse app and it works perfectly. It also opens the drawer automatically. For now, I give this printer a 10/10, taking into account the quality/price ratio. Any Thermal 80mm printer with Ethernet interface does not cost less than €150.00
I spend many hours on the computer and so I wanted some headphones to listen to music mainly while I work. I didn't need anything spectacular, just comfortable headphones with a long enough cable and a good sound. After seeing the price and reading the descriptions, I decided on these and although I have only used them for a couple of days I am still very happy with the purchase. Very good value for money. Lightweight, comfortable and very good sound. I'd buy them back.
