The resin can be finished into a much better quality when removed from printer.
Nice colour, but sadly not so good at print quality unless you finish surfaces yourself on the support side. Then you can have nice pieces/parts. I have used many of resins from Siraya blu/clear and Elegoo. This resin loses print quality on the support side a lot. I've tried heating the vat/tank. The resin seems to cling to the support side and cures. The cheaper Elegoo red outperforms this resin but it is more brittle. The detail is much higher on Elegoo resin. So basically I would say this resin is just ok by itself. However the resin can be finished by hand to give you exceptional pieces. Nice colour when polished into glass effect. You need to finish the product yourself for pristine finish. See my YouTube on how to do this. (Jeffrey Henderson)

Difficult to use
I heard great things about this resin but the long exposure time and tendency to lose detail on the support side of the print is really frustrating. Definitely not the easiest resin to use,

This resin really stinks, pleasant almond smell? No it’s horrible gets in your throat my wife can’t stand it. I printed an air filter using a 120mm hydroponics carbon filter to solve it and now get fresh air out. It still smells bad when the print is removed and washed though. A little bit creates a lot of odour. It’s very strong. I printed a small sight mount and could not break it with large pliers. It’s a very impressive resin. I found there was no audible separation with the film. Most important it was a full bottle not like other resins so consider that when price comparing. I found that ipa cleans it but not as easily as other resins. It turned my ipa white with globs floating around after just a couple of washes. It’s very gloopy and doesn’t drain off as well as other resins. Overall for those strong parts it’s great

Casi termino la botella, ¿mi conclusión? Gran resina, sin impresiones fallidas, sin deformaciones, impresiones fuertes y estéticamente agradables. Como la resina es bastante espesa, la imprimo a 35°C con el calentador de mi cámara de resina. Tenga en cuenta que a esa temperatura debe reducir el tiempo de exposición.

First off, i want to take a star off just for the sake of being mislead, its not 1Liter, its alota bit less, its about about .8L so it does feel like we're being skimmed. I've purchased two bottles so far and they were equally under filled. But. I'm blown away with the performance that its created a bias. I printed a face mask @ 1mm wall thickness with 20% infill, and dropped it from about 4m, it did scuff, but no cracks, no breaks, nada. Its not indestructible, but it surely does hold its name as a premium resin. PLA+ or Fast resin equivalent would have shrapnel'd at that height. Its resolution is decent, but it tends to warp severely around the supports to the point it will make a flat surface look like a bee sting, so alot of supports will severely distort your item, the plus side is sanding is very simple and can easily be smoothed out; on the downside this means it also scuffs very easily, so you may want to spray your parts with a clear to give it some scuff resistance.

Prints well, but by far the stinkiest resin I owe.

このレジンで作成したものはかなり… 異様な強度です。 浴槽の破損した水道管トラップとして作成、取り付け後にちょっと設計を間違えていたことに気がついて取り外そうとしたところ… 硬い。 厚さは最高でも4mmでしたが、ハンマーとマイナスドライバーで何度叩いても割れない。 最終的に30分は叩き続けたり、はまりこんでいたステンレス製の水道管を叩き広げる暴挙でどうにか抜去。 中々に間抜けな所業ですが、そのくらい硬く粘り強いレジンです。

The resin appears to continue to cure after after the print. My VAT was filled with chunks and blobs of resin despite the print coming out complete. The print are also horribly inaccurate and look to be unable to print a single sharp edge. No other resin brand has ever done this. For context my printers are set up in in a purpose made, light sealed, temperature controlled cabinet. I've read the only way to improve the resin is to mix with other brands, which I'm yet to try but I don't think ill waste my time.
