SKE Crystal 600 Pro Hands-On Review: A Week With the Cult Favourite
Seven days of daily use with the Crystal 600 Pro and what we found.
Browse Pod Kits Shop E-LiquidsQuick answer: A week with the Crystal 600 Pro confirmed its reputation. Flavour was strong and accurate from day one, the draw feel was consistently smooth, the device survived daily pocket carry without issue, and the LED glow remained an enjoyable touch throughout. At moderate use the device lasted just over five days, which is at the better end of real-world performance for a 600-puff rated device.
Short reviews capture a first impression. A week of daily use reveals how the Crystal 600 Pro performs when it becomes your only device. Here is what that week looked like.
Day-by-Day Findings
| Day | Puff count (approx.) | Observation |
|---|---|---|
| Day 1 | ~110 | Excellent first draw after priming. Watermelon Ice flavour vivid and accurate. LED glow more noticeable in dim indoor light than expected. Draw resistance close to a cigarette. |
| Day 2 | ~125 | Flavour identical to day 1. Device survived back pocket and bag carry with no damage. Morning first draw slightly thinner; normalised after 2 primer puffs. |
| Day 3 | ~120 | No change in flavour or vapour quality. Device beginning to feel lighter (noticeable liquid reduction). LED glow unchanged. |
| Day 4 | ~100 | Flavour still strong. Device used in cold outdoor conditions (approximately 4 degrees Celsius); first draw slightly thin until device warmed in hand. |
| Day 5 | ~85 | First signs of flavour reduction in final draw of the day. Still satisfying across the session. Device on its last quarter. |
| Day 5 (end) | Final puffs | Persistent dry note on last 10 to 15 draws. Replaced device before burnt stage was reached. Total puffs: approximately 540. |
One-Week Scorecard
| Criterion | Score | Notes |
|---|---|---|
| Flavour accuracy | 4.5/5 | Watermelon Ice was vivid throughout the first four days; reduced slightly on day 5 |
| Consistency draw to draw | 4.5/5 | Remarkably consistent; occasional thinner draw when device was cold |
| Build durability | 5/5 | Survived five days of pocket and bag carry with zero visible damage or functional issues |
| Nicotine satisfaction | 5/5 | 20mg nic salt consistently managed cravings; 3 to 5 puffs reliably effective |
| Real-world puff count | 4/5 | ~540 of rated 600; within expected range given 2 to 3 second draws |
| Overall | 4.5/5 | One of the best single-use disposables tested in its category |

Frequently Asked Questions
540 from a rated-600 device is a 90% yield, which is at the better end of real-world performance. This reflects use of 2 to 3 second draws rather than very long draws, and reasonable pacing between puffs. Users who take longer draws or chain vape will typically get fewer puffs. Users who vape very lightly and slowly may exceed 540. The range for most users is 480 to 580 effective puffs.
Flavour category affects perceived quality but not puff count. Iced variants (like Watermelon Ice) are among the most consistent performers because the menthol cooling compensates for any slight coil temperature variation. Sweeter non-iced fruit flavours can show more variation as the coil ages in the final quarter. For maximum flavour consistency across a week of use, iced or menthol variants are the best choice.
Yes, clearly. The mesh coil difference is noticeable across a full week. The standard Crystal Bar would likely show more flavour fade on day 4 and 5 than the 600 Pro demonstrated. For daily users the upgrade is worth the marginal cost difference at every retailer.
Given the June 2025 ban on single-use disposables, the natural successor is the Crystal Plus pod kit. It replicates the SKE flavour experience in a rechargeable format, with each pod delivering the same ~600 puffs as a Crystal 600 Pro. The battery charges overnight and is reused, eliminating the weekly device replacement cycle entirely.
