They are very beautiful and easy to installAbsolutely love! Yes, it had a line going through the sides, my opinion, doesn’t bother me at all. Yes, I can foresee having to clean it, and you have to clean it before you install it (it has a powdery type substance on it- making it appear to look like scratches on the glass). A Microfiber cleaning rag worked great. It’s beautiful, simple, makes a statement without visually taking up space, lots of light, and beautiful shadows on the ceiling. Glad I took a chance and ordered it on line, I bought the smaller version (over the sink) and three medium size for the kitchen island. They are huge, no problem for the hubs to install and good value compared to other lights (PB).My wife and I love this! We were concerned after having read that there was a seam in the glass (which most people believe means that this wasn't hand blown, I'll get to that in a second), but once the light is hanging the seam isn't an issue for us. Overall the piece looks fantastic in our dining room and we couldn't be happier. We put an LED Edison bulb in it and it gives off a ton of light. We also placed pieces of colored beach (sea) glass around the bottom to add a touch of color.Now, onto the concern of this not being hand blown. So, having blown glass for four years I would have to say that this item is most likely hand blown. (I could be wrong, but this is my educated opinion.)Reasons for my opinion are as follows: The seams appear to be from a mold into which the molten glass was placed while on the end of a blow pipe before blowing so that the glassblowers could get uniform shape and size for each of the lights produced. The mold would need to be made from two separate pieces in order to get the shape and still remove the glass from the mold without damaging it. Hence a seam from where those two pieces would sit together. Without the use of a mold these lights would, most likely, be slightly different sizes, shapes and be much more costly to produce than what is being sold here. Also, the "hammering" was most likely created by using a mold that had a hammered texture to it to begin with. There is also a lip wrap near the top of the light.Odds are this was all done in a factory setting so that these could be more quickly produced, but that doesn't mean that there weren't people actually blowing the glass.So, to sum up: excellent product; hangs well in our dining room; yes, my educated opinion is that it is hand blown.Large and beautifulI bought two of these lights. One for over my kitchen sink and the other one for over my dining room table. The kitchen one is the middle size, and the dining room has the large one.I’m amazed at how pretty they are!I purchased Edison lightbulbs for them, and they look really great. Edison bulbs aren't the brightest bulbs on the planet (pun intended), so I could have benefited from having two medium lights over the dining table vs the one big light, but I’m happy with what I did. It’s not really bright, but it will be fine.The light fixture is elegant and casts a beautiful light. I’m so happy with them that I’m purchasing a third one for my hallway.And yes, like other reviewers have mentioned there is a noticeable line down two sides of the glass. I have decided that the benefits of this beautiful light outweigh this visible line. To the casual eye, I think I’m the only one who would notice.This is an amazing product. I have been searching high and low for this style that I have seen in many model homes. I am so happy that this is on Amazon. I did read a lot of other reviews and people were talking about the seam on the glass. It's actually not a true seen. I purchased a 13 inch clear. The quality is amazing, the installation was super easy. I would advise you to get the hanging length right and market with a white marker on each of the lights if you are installing more than one light. That way each of your lights hangs evenly. Once these were up, a completely Transformed the look of the kitchen. This is exactly what I was going for. The black is also a nice touch if you have a room of similar colors. It gives a nice contrast. I highly highly recommend this light. Shipping was super fast. Even though it said it was going to be longer it actually came significantly.I absolutely love my new pendant lights! They are the perfect way to finish off my new kitchen. We just moved in to our brand new build home and needed to start adding our own personal touches, these pendants do that. The size makes them a statement but there is nothing obtrusive about them. I am using grey tint Edison bulbs and they look perfect and cut down on the pattern on the ceiling.The product arrived on time and they are installed in my kitchen. They are quite exquisite and enhance the decor of the kitchen. I found it difficult to get the correct bulbs .... filament LED with an amber glow. When I first opened the parcel, I thought they would be too large but not. My kitchen is large enough to accommodate them. The smokey colour is just right for the kitchen decor. Very much admired by the constant stream of tradespeople and visitors> I would purchase from this vendor again.
